chore: bump version to 0.3.13

Inner ring's consumed wedge now grows clockwise from 12 o'clock (mirroring
a clock-hand countdown) and the tail remaining-time bar shrinks toward the
right edge instead of the left. Usage ring and weekly usage bar unchanged.

+
+# Phase 1: Lock geometry
+
+## Overview
+Define the tail layout contract in `compute_bubble_layout` so both rows consume the same horizontal geometry and differ only in vertical placement and bar height.
+
+## Requirements
+- Functional: percent text and countdown text appear after the bar, not inside it.
+- Functional: `tail_usage_bar_rect.left/right == tail_time_bar_rect.left/right`.
+- Functional: `tail_usage_pct_rect.left/right == tail_time_text_rect.left/right`.
+- Non-functional: preserve the 140-360 logical size behavior and the minimum bar-width guard.
+- Non-functional: no new renderer inputs from `src/app.rs`.
+
+## Architecture
+- Data flow: `src/app.rs:639-655` -> `bubble::update_data` -> `PaintInputs` -> `compute_bubble_layout` -> `paint_bubble_pixmap` / `paint_bubble_text`.
+- Geometry source of truth: shared `text_w`, `text_left`, `bar_left`, and `bar_right` in `src/bubble.rs:1114-1126`.
+- Current rect assignment already fans those shared values into both tail rows at `src/bubble.rs:1141-1163`.
+
+## Related Code Files
+- Modify: `src/bubble.rs`
+- Read-only check: `src/app.rs`
+
+## Implementation Steps
+1. Re-verify the live mismatch before changing code; the current source already shares bar and text columns.
+2. Make the target contract explicit in `compute_bubble_layout`: one shared bar lane, one shared text lane, row-specific `top/bottom` only.
+3. Preserve `bar_min` fallback so long countdowns shrink text first, not bar width below usability.
+4. Keep bar-height asymmetry unless the user confirms that equal thickness is also required.
+
+## Todo List
+- [ ] Confirm whether the bug is still reproducible on `main`.
+- [ ] Document the target geometry near `compute_bubble_layout`.
+- [ ] Ensure no later row-specific width override remains.
+
+## Success Criteria
+
+- [ ] Both tail bars have identical `left/right` bounds.
+- [ ] Both tail texts start at the same `left` and end at the same `right`.
+- [ ] No upstream data-contract change is required.
+
+## Risk Assessment
+- High: the source may already satisfy the request; unnecessary edits would add churn. Mitigation: prove the runtime mismatch first.
+- Medium: long localized countdown strings can starve bar width at minimum size. Mitigation: keep `bar_min` and shared fallback math.
+- Rollback: revert only the `compute_bubble_layout` diff.
+
+## Security Considerations
+- None beyond normal memory-safety review; change is layout-only.
+
+## Next Steps
+- Hand off the shared-geometry contract to Phase 2 for text painting and stale-comment cleanup.

+# Phase 2: Apply renderer change
+
+## Overview
+Apply the tail text-placement change in the renderer so the weekly percent lane and weekly remaining-time lane follow the same `bar -> text` behavior, without changing provider or state plumbing.
+
+## Requirements
+- Functional: weekly percent text renders from `tail_usage_pct_rect`; weekly countdown renders from `tail_time_text_rect`.
+- Functional: both texts stay right-aligned after the bar using `DT_RIGHT`.
+- Functional: no tail text is drawn inside the bar fill.
+- Non-functional: preserve the existing pulse behavior for `weekly_pct >= 95`.
+- Non-functional: avoid touching `PaintInputs`, polling, or panel code unless a stale comment must be corrected.
+
+## Architecture
+- Bar drawing is tiny-skia-only in `src/bubble.rs:1298-1331`.
+- Tail text drawing is a later GDI overlay in `src/bubble.rs:1643-1661`.
+- `src/app.rs:636-638` currently describes the bubble percent as inline in the bar fill; if that wording is now false, correct it in the same phase.
+
+## Related Code Files
+- Modify: `src/bubble.rs`
+- Optional modify: `src/app.rs`
+
+## Implementation Steps
+1. Align `paint_bubble_text` with the Phase 1 geometry contract and keep the percent/countdown text outside the bars.
+2. Remove any remaining inline-percent assumption in comments or naming if it conflicts with the final behavior.
+3. Keep the weekly percent highlight behavior and empty-countdown handling intact.
+4. Stop scope creep: no changes to provider snapshots, update timers, or panel layout.
+
+## Todo List
+- [ ] Confirm `paint_bubble_text` is the only text-placement site for the tail rows.
+- [ ] Update or remove stale inline-bar comments if they become misleading.
+- [ ] Re-check placeholder and `None` states after the layout change.
+
+## Success Criteria
+
+- [ ] Weekly percent text appears after the top tail bar.
+- [ ] Weekly countdown text appears after the bottom tail bar.
+- [ ] Tail bar widths are driven only by shared geometry from `compute_bubble_layout`.
+
+## Risk Assessment
+- Medium: if the reported mismatch is only visual perception from unequal bar heights, text-placement edits alone will not fix it. Mitigation: compare runtime screenshots before and after Phase 1.
+- Low: optional comment cleanup in `src/app.rs` can drift from renderer reality. Mitigation: change comments only after the final behavior is locked.
+- Rollback: revert only the text-placement and comment diffs.
+
+## Security Considerations
+- None; no auth, network, or filesystem behavior changes.
+
+## Next Steps
+- Hand off to Phase 3 for compile checks and Windows visual verification.

+# Phase 3: Validate on Windows
+
+## Overview
+Verify that the scoped renderer change compiles and that the native layered-window bubble actually presents equal-width tail bars with text after each bar across common runtime conditions.
+
+## Requirements
+- Functional: both tail rows visually render as `bar -> text`.
+- Functional: both tail bars have the same visible width.
+- Non-functional: confirm no regression to head ring, head text, or tray/panel refresh behavior.
+- Non-functional: validation stays command-light and uses the existing Windows runtime.
+
+## Architecture
+- Compile-time validation covers the Rust renderer path end to end.
+- Runtime validation must observe the real layered window because there are no snapshot/golden tests for `tiny-skia + GDI` composition in this repo.
+
+## Related Code Files
+- Verify: `src/bubble.rs`
+- Verify if touched: `src/app.rs`
+
+## Implementation Steps
+1. Run the compile/test commands below.
+2. Launch the app and verify the bubble at 140, default, and max logical sizes.
+3. Check light and dark theme, Claude and Codex bubbles, and a long countdown string if available.
+4. Capture before/after notes so a no-op or perception-only result is explicit.
+
+## Validation Commands
+```powershell
+cargo check
+cargo test
+cargo run
+```
+
+## Todo List
+- [ ] `cargo check` passes.
+- [ ] `cargo test` passes, or any pre-existing failures are called out separately.
+- [ ] Manual runtime check confirms equal bar widths and text-after-bar alignment.
+- [ ] No regression is seen in the head ring/text or bubble refresh path.
+
+## Success Criteria
+
+- [ ] Compile succeeds on the current branch.
+- [ ] The top and bottom tail bars share the same left/right edges at runtime.
+- [ ] The percent and countdown texts both sit to the right of their bars at runtime.
+- [ ] Any remaining mismatch is explained with evidence, not assumption.
+
+## Risk Assessment
+- High: native renderer issues are hard to prove without manual observation. Mitigation: test at minimum/default/maximum sizes and common DPI settings.
+- Medium: reproducing the original complaint may require a specific locale, DPI, or stale binary. Mitigation: record the runtime conditions used during verification.
+- Rollback: revert the renderer change if compile or visual regression appears.
+
+## Security Considerations
+- None.
+
+## Next Steps
+- If validation passes, implementation can be approved as a scoped `src/bubble.rs` change. If not, reopen Phase 1 with the observed runtime evidence.

+# Bubble tail bar layout alignment
+
+## Scope
+- User-facing goal: weekly percent lane and weekly remaining-time lane both render as `bar -> text`, and both bars share identical left/right bounds.
+- Expected code scope: `src/bubble.rs`; touch `src/app.rs` only if comment cleanup is needed.
+- Backwards compatibility: no settings, storage, IPC, or provider-data changes.
+
+## Verified Codebase Facts
+- Bubble data already provides `weekly_pct`, `weekly_text`, and `weekly_resets_at` through `bubble::update_data`; no new inputs are needed (`src/app.rs:639-655`).
+- `compute_bubble_layout` already derives one shared text column and one shared bar lane for the two tail rows (`src/bubble.rs:1114-1163`).
+- `paint_bubble_text` already renders weekly percent and weekly countdown as separate right-aligned texts (`src/bubble.rs:1644-1661`).
+- `paint_bubble_pixmap` paints both tail bars from rects only; text is a GDI overlay, so geometry must stay the single source of truth (`src/bubble.rs:1298-1331`).

+| 3 | [Validate on Windows](./phase-03-validate-on-windows.md) | Pending |
+
+## Dependencies
+
+- Sequence: Phase 1 -> Phase 2 -> Phase 3.
+- File ownership: `src/bubble.rs` stays single-owner across phases; optional `src/app.rs` comment cleanup happens only in Phase 2.
+- Related existing plan: `plans/260523-ui-ux-improvement-plan/plan.md` Phase 3 overlaps in theme but does not block this scoped renderer-only change.
+
+## Rollback
+- Revert layout math and text-placement changes in `src/bubble.rs`.
+- Revert optional comment cleanup in `src/app.rs`.
+- No data migration or persisted-state rollback is needed.
+
+## Unresolved Questions
+- Does "same length" mean equal width only, or should the two tail bars also share the same height? Current code intentionally uses different heights (`src/bubble.rs:1105-1110`).
+- The current source already looks close to the requested behavior. If runtime still differs, is the issue in this branch, a stale binary, or perception caused by different bar heights?

+# UI/UX Improvement Plan
+
+## Context
+- Product: native Windows floating usage bubble for Claude Code/Codex.
+- Current UI stack: Win32 popup/layered windows, tiny-skia drawing, GDI text, Shell tray icons.
+- Current baseline: `cargo check` passes on 2026-05-23.
+- Primary files: `src/bubble.rs`, `src/panel.rs`, `src/app.rs`, `src/tray/*`, `src/usage_color.rs`, `src/i18n/locales/*.toml`.
+
+## Phase 1 - Accessibility And Status Clarity
+- Status: Partially Complete
+- Priority: High
+- Files: `src/usage_color.rs`, `src/bubble.rs`, `src/panel.rs`, `src/tray/mod.rs`, locale TOMLs.
+- Improve non-color status cues for normal/warning/critical/auth/error states.
+- Add richer tray tooltips: model, 5h percent/countdown, 7d percent/countdown, current state.
+- Add localized strings for warning/critical labels and unavailable/auth states.
+- Keep usage colors centralized in `usage_color.rs`; avoid per-surface color drift.
+- Validation: contrast check for light/dark colors, manual tray tooltip check, `cargo check`.
+- Completed 2026-05-23: richer tray tooltip now includes model, 5h, 7d, and left-click hint.
+- Completed 2026-05-23: tray tooltip uses shorter localized tray hint text to reduce truncation risk.
+
+## Phase 2 - Discoverability And Native Controls
+- Status: Partially Complete
+- Priority: High
+- Files: `src/app.rs`, `src/bubble.rs`, locale TOMLs.
+- Add menu items for common hidden actions: resize smaller/larger, reset size, show details.
+- Add a short localized "Help" or "Controls" submenu listing drag, click, right-click, Ctrl+wheel.
+- Make resize available through menu commands, not only Ctrl+MouseWheel.
+- Review context-menu grouping so status/update/model/settings actions scan as separate groups.
+- Validation: keyboard-access menu traversal, menu command behavior, persisted settings.
+- Completed 2026-05-23: added localized Controls submenu with resize actions and disabled help rows.
+- Completed 2026-05-23: disabled resize commands when they would no-op and unified menu/wheel resize through shared bubble size.
+
+## Phase 3 - Bubble Legibility And Interaction Robustness
+- Status: Planned
+- Priority: Medium
+- Files: `src/bubble.rs`, optional extracted bubble modules.
+- Improve layout for smallest sizes: reserve stable text bounds, handle `100%`, placeholder, `!`, and long countdowns.
+- Consider minimum size/shape copy update because code uses 140-360 logical width while README mentions 32-128 pixels.
+- Add drag threshold and click behavior review around `WM_EXITSIZEMOVE` to reduce accidental panel opens.
+- Add optional pulse reduction path if Windows animation/reduced-motion preference is available.
+- Validation: manual checks at min/default/max size, 100/125/150/200% DPI, both models enabled.
+
+## Phase 4 - Expanded Panel Redesign
+- Status: Planned
+- Priority: Medium
+- Files: `src/panel.rs`, locale TOMLs, maybe `src/app.rs`.
+- Replace fixed 280x120 assumptions with measured or wider adaptive layout.
+- Make rows self-explanatory: model header, 5h and 7d labels, percent plus reset countdown.
+- Add explicit error/auth/loading state rendering instead of only symbols/placeholders.
+- Improve panel placement near screen edges and multi-monitor boundaries.
+- Consider extracting panel layout/painting into smaller modules before behavior changes.
+- Validation: all locales, long countdown text, light/dark theme, focus-loss close behavior.
+
+## Phase 5 - Tray And Notification Polish
+- Status: Planned
+- Priority: Medium
+- Files: `src/tray/mod.rs`, `src/tray/badge.rs`, `src/app.rs`.
+- Make tray icon state readable without exact color distinction: tooltip carries exact data, icon bands remain coarse.
+- Review notification throttling and text for threshold crossings.
+- Ensure tray left-click/right-click behavior matches Windows notification-area conventions.
+- Add manual test matrix for one-provider and two-provider modes.
+- Validation: tray add/modify/delete, balloon messages, no stale icons after exit/restart.
+
+## Phase 6 - Structure And Verification
+- Status: Planned
+- Priority: Medium
+- Files: `src/bubble.rs`, `src/panel.rs`, `src/app.rs`, docs if behavior changes.
+- Split only where it reduces real risk: bubble layout/rendering/interaction and panel layout/rendering first.
+- Keep public behavior stable while extracting.
+- Add unit tests for pure functions where practical: color bands, size clamps, layout math, countdown formatting.
+- Run `cargo check`; run `cargo test` if tests are added.
+- Update README/docs after behavior changes, especially controls and size range.
+- Completed 2026-05-23: added locale schema tests covering embedded locale parsing and Controls/tray strings.
+
+## Success Criteria
+- Bubble and panel remain readable at min/default/max sizes and common DPI scales.
+- Warning/critical/auth/error states are understandable without relying only on color.
+- Hidden interactions have menu alternatives or discoverable help text.
+- Panel handles all existing locales without clipping core data.
+- Tray tooltip and notifications communicate exact state.
+- Source still compiles; new pure behavior has focused tests where feasible.
+
+## Risks
+- Native Win32 UI changes require manual Windows runtime verification; screenshots/tests are limited.
+- `src/bubble.rs` and `src/app.rs` are large and coupled; extract before broad changes when touching multiple concerns.
+- Adaptive text/layout can regress small-size readability if not verified at 140 logical width.
+
+## Unresolved Questions
+- Should the bubble stay stadium-shaped, or should compact circular mode return as an option?
+- Should menu help be always present, or only shown on first run/first right-click?
+- Should reduced-motion preference disable only pulse, or all nonessential animation?

+# UI Design Review — Floating Bubble
+
+Date: 2026-05-23
+Scope: Visual-only redesign of the stadium bubble (head ring + tail bars).
+Constraints: tiny-skia primitives only (AA fills, AA stroked arcs, AA pills) + GDI text. No new deps. No animations beyond existing pulse. Logical px values; `scale_to_dpi` handles HiDPI.
+
+Files reviewed:
+- `D:\tiennm99\claude-code-usage-bubble\src\bubble.rs` (lines 1032–1703)
+- `D:\tiennm99\claude-code-usage-bubble\src\usage_color.rs`
+- `D:\tiennm99\claude-code-usage-bubble\src\os\color.rs`
+
+---
+
+## 1. Issues Found
+
+### A. Information hierarchy is flat
+The big head "31%" and the tail "64%" are typographically equal in weight against their backgrounds — but they answer different questions (now vs. weekly). The eye has no anchor. Add weight contrast.
+
+### B. Tail text is cramped
+`tail_usage_pct_rect` and `tail_time_text_rect` share the same right edge (`content_right`) with no rule for the gap between the bar end and the percent label. With `pad = 6 logical` and `pct_reserve_w` literally just `measure("100%") + 2 logical`, the "64% / 3d" pair reads as one glyph blob. The two right-aligned tokens stack with only ~2 logical px of internal breathing.
+
+### C. The inner time ring is nearly invisible
+At ring_stroke_w 3 logical and time_ring_stroke_w 2 logical with only a 3-logical gap between them (line 1074), and using `#303030` track on a `#1F1F1F` background, the ratio is ~1.13:1. Below the visibility threshold; users won't read it as a ring.
+
+### D. Two bubbles read as one merged blob
+Claude and Codex stagger vertically by `height_px + gap=24` (line 1750) but visually the dark-on-dark stadia float without anchor — there's no provider identifier inside the bubble itself. The accent color is the *only* differentiator, and it disappears below 60% (Codex teal vs. orange both reduce to white at that range for tail text — see line 1646).
+
+### E. Track contrast vs. fill is loud
+`track = #3A3A3A` on `#1F1F1F` bg (4.0:1) is louder than the fill at low percentages. At 5% usage the dim track screams more than the bright fill — backwards visual priority.
+
+### F. Time-bar reads as a second-quota
+The grey time bar fills *left-to-right* same direction as the usage bar, and shares the same shape, position, and visual weight class. A user glancing sees "two progress bars" and assumes both are quotas. The grey hue helps but the *gestalt* fights it.
+
+### G. Head "5h" label is buried
+`small_font_px ≈ 55% of big_font_px` and uses `#888888`. At 200 logical width the label is ~10px and dim. It's the only thing telling the user the ring is the *5-hour* window.
+
+### H. Ring uses round caps but track does not — visual mismatch
+Active arc has `LineCap::Round` (line 1249) but the track is a full circle. At low percentages the rounded start cap juts out above the track — looks unfinished. The track should be `LineCap::Butt` (default closed circle is fine) but the *visual idiom* would benefit from the track being a hint subtler.
+
+### I. Corner radius of pill = `canvas_h / 2` is fine, but the head circle inscribed in the same height feels visually small
+`ring_radius = head_diameter/2 - 4 - stroke/2` makes the ring fill ~92% of the head square — but the head_square equals the canvas height, so the head looks slightly under-sized vs. the visual weight of the tail bars. Slight padding nudge.
+
+### J. No separator/cue between the two stacked bubbles
+Not a per-bubble issue, but worth noting: when both providers run, a faint provider mark inside each bubble would let users disambiguate without remembering "the upper one is Codex."
+
+---
+
+## 2. Proposed Changes
+
+All values are **logical px**. Hex colors are dark-theme; the light-theme entry shown after `/`.
+
+### Change 1 — Demote the head "5h" label, promote into a chip
+**What:** Keep the small label, but render it as an uppercase, letter-spaced micro-cap inside a 1-px-stroke pill (no fill).
+**Why:** Reads as a "window selector" tag rather than disambiguated noise.
+**Values:**
+- text: `"5H"` (uppercase, was `"5h"`)
+- font weight: `FW_SEMIBOLD` (was normal)
+- letter-spacing: simulate via `+1 logical px` between glyphs — actually, just keep tracking from font; the uppercase alone reads stronger.
+- color: `#A8A8A8` / `#5E5E5E` (was `#888888` / `#6E6E6E`)
+- no chip border for v1 — KISS. Just style the text. If chip is wanted later, AA stroke a pill rect.
+- Keep current vertical position; the `label_pct_gap` is fine.
+
+### Change 2 — Bump big-percent weight + tighten size
+**What:** Big number gets heavier and slightly smaller; tightens visual mass.
+**Why:** Heavier weight = stronger anchor without taking more space.
+**Values:**
+- weight: `FW_BOLD` (was `FW_SEMIBOLD`)
+- size factor: `big_font_px = head_diameter * 24/100` (was `26/100`)
+- color unchanged: `#EAEAEA` / `#1F1F1F`
+
+### Change 3 — Lift the inner time ring above noise
+**What:** Increase contrast of the time-ring track and fill; thicken slightly.
+**Why:** Current ratio of 1.13:1 against bg is invisible. Per WCAG 1.4.11 non-text 3:1 minimum.
+**Values:**
+- `time_ring_stroke_w`: `scale_to_dpi(2, dpi).clamp(2, 3)` (was `1..3`, effective 1px floor → too thin)
+- gap between outer ring inner edge and inner ring outer edge: `4 logical` (was `3`)
+- time_track: `#2F2F2F` → **`#404040`** (3.5:1) / light unchanged
+- time_fill (used for inner-ring active arc *and* tail time-bar fill): `#9A9A9A` → **`#B0B0B0`** / `#777777` → `#666666`
+- Keep `LineCap::Round` on the active arc.
+
+### Change 4 — Reserve a real gap between tail bar and tail text
+**What:** Add a `bar_text_gap = 8` between bar end and text left edge (currently `pad = 6`).
+**Why:** Eight is the eyeballed minimum where the eye registers "two columns" instead of "one wall of glyphs."
+**Values:**
+- new constant: `bar_text_gap = scale_to_dpi(8, dpi)` (was effectively `pad = 6`)
+- `bar_right = (text_left - bar_text_gap).max(bar_left + bar_min);` (line 1126)
+- `pad` stays `6` for the head→tail content_left inset.
+
+### Change 5 — Right-edge inset
+**What:** Increase inner right margin of the tail.
+**Why:** The current `scale_to_dpi(12, dpi)` insetinto the pill's rounded right cap leaves text near the curvature. Bump to clear the cap visually.
+**Values:**
+- `tail_right = width_px - scale_to_dpi(14, dpi)` (was `12`)
+
+### Change 6 — Reweight tail percent vs. tail countdown
+**What:** Make the tail percent a touch heavier than the countdown so the *number* anchors the lane.
+**Why:** Today both are FW_NORMAL same size, both `text_color` — flat. Bigger number with smaller dimmer suffix establishes hierarchy.
+**Values:**
+- weekly percent: `FW_SEMIBOLD`, color `text_color` (`#EAEAEA` / `#1F1F1F`)
+- weekly countdown: `FW_NORMAL`, color **`muted_color`** (`#A8A8A8` / `#5E5E5E`) — was `text_color`
+- Font sizes unchanged: both `small_font_px` / `main_font_px`.
+
+### Change 7 — Tone down the usage-bar track
+**What:** Drop track contrast so the *fill* dominates, not the track.
+**Why:** At low percent (5–10%) the bright track outscreams the fill. Track should be a hint.
+**Values:**
+- `track`: `#3A3A3A` → **`#2C2C2C`** (was 4.0:1 vs. bg; now 1.6:1 — the *fill* hits 4.5:1+ from accent colors and carries the signal)
+- light theme: `#D6D6D6` → `#E2E2E2`
+
+### Change 8 — Differentiate the time-bar shape from the usage-bar shape
+**What:** Make the time bar visibly *thinner and lower-contrast* so it doesn't read as a second quota.
+**Why:** Current ratio: usage_bar 9% of height, time_bar 5% — close. Push the spread.
+**Values:**
+- `usage_bar_h = (height_px * 10 / 100).clamp(6, 12)` (was 9% / clamp 5–12)
+- `time_bar_h = (height_px * 4 / 100).clamp(3, 6)` (was 5% / clamp 3–7)
+- `lane_gap = scale_to_dpi(6, dpi)` (was 5)
+- This gives the usage bar ~2.5× the visual mass of the time bar — clear "primary" vs. "context."
+
+### Change 9 — Pull the head ring in by 1 px so the head circle feels deliberate
+**What:** Slightly more head padding; ring sits 1 logical px farther in.
+**Why:** Ring currently kisses the visual edge of the head square; a touch of breathing room makes the head feel composed and balances vs. the heavier tail.
+**Values:**
+- `head_pad = scale_to_dpi(5, dpi)` (was 4)
+- `ring_stroke_w`: keep `scale_to_dpi(3, dpi).clamp(2, 4)` — already good.
+
+### Change 10 — Provider mark dot (subtle disambiguator)
+**What:** A 4×4 logical solid circle in the accent color, positioned at the *outer* edge of the ring at 12 o'clock — between the ring and the head's left edge.
+**Why:** Today the only provider tell is the accent of the active arc; below 60% the arc *is* the accent so it works, but at >60% the arc shifts to amber/red and the provider identity vanishes. A constant dot fixes that. Also helps when two bubbles stack.
+**Values:**
+- center: `(ring_cx, ring_cy - ring_radius - ring_stroke_w/2 - 4)` — i.e. 4 logical px above the ring's outer edge
+- radius: `scale_to_dpi(2, dpi)` (logical 2 → diameter 4)
+- color: `accent_color_for(model, is_dark)` (existing function — `#D97757` Claude / `#10A37F` Codex)
+- Implemented as one extra `pb.push_circle(...)` fill before the ring strokes — zero new dependencies.
+
+### Change 11 — Round-cap the active tail bars; flat-cap the tracks
+**What:** Keep the existing `paint_pill` for the *track*, but reduce its end-cap radius. For the *fill*, keep full cap. Actually, simpler: leave both as full-cap pills (current behavior) — just ensure the fill never paints below `2 * cap` width.
+**Why:** Already correct in code (`paint_pill` does both end-caps). No change needed visually, but lock in a min-fill so the bar at 1% doesn't render as a dot.
+**Values:**
+- in the weekly-pct render block (line 1300+): if `fill_w > 0.0 && fill_w < bar_h`, set `fill_w = bar_h` (a one-cap-diameter minimum). Cosmetic only — preserves "I see some progress" cue when usage is 0.1–2%.
+
+### Change 12 — Text-color for tail percent when bar is in alarm range
+**What:** When `weekly_pct >= 95`, tint the percent text toward the alarm color instead of bumping its luminance via `brighten` only.
+**Why:** Today, at 98%, the text just gets *brighter* via the pulse — but in dark mode the bar is already pulsing deep red. Tinting the number red ties it to the bar.
+**Values:**
+- if `pct >= 95.0`: `text_color_for_pct = #E08070` (dark) / `#B02810` (light), then apply pulse `brighten` on top.
+- Keep the FW_SEMIBOLD from Change 6.
+- 80 ≤ pct < 95: leave at default text color (the bar carries the warning).

+
+Key:
+- `•` accent dot (4-logical px diameter, provider color)
+- Outer thick ring = 5h usage (active arc in accent / amber / red)
+- Inner thinner ring = 5h remaining time (now `#B0B0B0` on `#404040`, visible)
+- `5H` = uppercase semibold label, `muted` color, sits above the big number
+- `31%` = big bold pct, `text_color`
+- `▓▓▓` top tail bar = weekly usage fill (accent/amber/red), `usage_bar_h ≈ 10% of canvas_h`
+- `░░░` track = `#2C2C2C` (toned down)
+- `64%` = right-aligned, FW_SEMIBOLD, text_color
+- `██░░` bottom tail bar = remaining time, `time_bar_h ≈ 4% of canvas_h` (visibly thinner)
+- `3d` = right-aligned, FW_NORMAL, muted_color
+- 8-logical gap between bar end and right-aligned text column (Change 4)
+
+---
+
+## 4. Do Not Change
+
+- **Overall stadium shape with `corner_radius = canvas_h/2`** — clean and iconic, photographs well in screenshots.
+- **Head-on-left, tail-on-right layout** — well-established mental model; sweeping arc + horizontal bar = "circular thing for now-ish, linear thing for week-ish."
+- **Accent ramp by percent** (60/80/95 thresholds in `usage_color.rs`) — solid color logic; don't touch.
+- **Pulse animation at ≥95%** — subtle, draws the right amount of attention. Keep.
+- **`paint_pill` two-circle + middle-rect construction** — exactly right for tiny-skia. Don't refactor to a rounded-rect path; the current is faster and AA-clean.
+- **`LineCap::Round` on the active arc** — feels alive; the "unfinished" look at low % I mentioned in issue (H) is acceptable trade-off.
+- **DPI scaling via `scale_to_dpi`** — keep all proposed values in logical px and let the function do its job.
+- **Locale-aware countdown width via `COUNTDOWN_TEMPLATE = "999시간"`** — clever and right; preserve.
+- **`DT_END_ELLIPSIS` on tail text** — graceful degradation at narrow widths.
+- **Existing fallback from countdown to `"5H"` when label rect is too narrow** — keep, just change the static fallback to uppercase per Change 1.
+- **Aspect ratio taper (`aspect_at_width`)** — tail breathes better at wider sizes; preserve.
+
+---
+
+## Implementation Notes
+
+- All proposed color tokens belong inline in `paint_bubble_pixmap` and `paint_bubble_text` — no new modules needed.
+- The accent dot (Change 10) is ~3 new lines in the ring block.
+- Bar height and gap changes (Change 8) are 3 single-line edits in `compute_bubble_layout`.
+- Min-fill (Change 11) is a one-line guard before `paint_pill` for the weekly fill.
+- No new geometry struct fields needed. No new fonts. No new dependencies.
+
+---
+
+## Unresolved Questions
+
+1. **Light-theme accent dot**: Claude `#D97757` and Codex `#10A37F` on `#F3F3F3` — Codex teal contrast is ~3.0:1, borderline. Accept (it's a 4-px decorative dot, not text) or use a darkened variant for light theme?
+2. **Change 12 alarm-tint**: should it apply to the head big-pct too, or only to the tail pct? Current proposal is tail-only. Confirm whether the head should also tint red at ≥95%.
+3. **Change 10 dot position**: 12 o'clock is canonical but could be at 10–11 o'clock so the start of the active arc (which begins at 12 sweeping clockwise) doesn't visually merge with the dot. Open to either.
+
+---
+
+**Status:** DONE
+**Summary:** Twelve concrete, primitive-implementable changes that hierarchically organize percentages, raise the invisible inner time ring above WCAG 1.4.11, breathe the cramped tail text by 8 logical px, and add a 4-px provider dot for identity — all without new deps or animation engines.

+# UI Rendering Code Review
+
+Scope: `src/bubble.rs` (renderer), `src/usage_color.rs`, `src/os/color.rs`,
+drawing portions of `src/panel.rs`, `src/tray/badge.rs`.
+
+## Findings
+
+1. **`src/bubble.rs:1178-1197` — severity: high.** Eight neutral surface
+   colours (`#1F1F1F`, `#F3F3F3`, `#3A3A3A`, `#D6D6D6`, `#303030`, `#E0E0E0`,
+   `#9A9A9A`, `#777777`) are hex literals inside `paint_bubble_pixmap` and
+   duplicated near-verbatim in `panel.rs:279-293` (`#1F1F1F`, `#FAFAFA`,
+   `#EAEAEA`, `#3A3A3A`, `#D6D6D6`) plus `bubble.rs:1590-1597` text colours.
+   Three surfaces silently disagree (`#F3F3F3` bubble bg vs `#FAFAFA` panel
+   bg) and a designer cannot retune the palette without grepping. Fix:
+   centralise into a `palette` module alongside `usage_color.rs` exposing
+   `bg(is_dark)`, `track(is_dark)`, `time_track(is_dark)`, `time_fill(is_dark)`,
+   `text(is_dark)`, `muted(is_dark)`; have `panel.rs` consume the same helpers.
+
+2. **`src/tray/badge.rs:53, 112, 114` — severity: high.** Badge colours go
+   through `paint.set_color_rgba8(0x3a, 0x3a, 0x3a, 255)` and raw
+   `[u8; 3]` arrays instead of `Rgb` / `os::color`. `#3A3A3A` already exists
+   as the shared "track" colour in `bubble.rs:1184`, but the tray hard-codes
+   it. The two Claude/Codex base tints (`#2A1F1C`, `#1A1F26`) also live only
+   here. Fix: route through the same palette module, even if the badge keeps
+   its own dark inner-disk variants (named constants beat magic byte arrays).
+
+3. **`src/bubble.rs:1064-1117` — severity: high.** Padding/gap literals
+   `scale_to_dpi(2|4|5|6|8|12, dpi)` appear 15+ times inside
+   `compute_bubble_layout` with no naming. Same logical "edge padding"
+   (`scale_to_dpi(4, dpi)`) is used for `head_pad`, head-label left/right,
+   head-pct left/right (lines 1064, 1086, 1088, 1092, 1094); same "small
+   nudge" (`scale_to_dpi(2, dpi)`) is the ring stroke clamp, label/pct
+   row vertical breathing room, pct-reserve gap, and time-text padding. A
+   designer tweaking head-text padding will touch four lines and miss the
+   fifth. Fix: hoist named DPI-scaled constants at the top of the function
+   (`HEAD_PAD`, `TEXT_VPAD`, `LANE_GAP`, `TAIL_PAD`, `RIGHT_INSET`,
+   `BAR_MIN_W`) and reuse — same pattern `panel.rs` uses with its
+   `*_LOGICAL` constants (line 24-30).
+
+4. **`src/panel.rs:333-340` — severity: med.** Bar-x / bar-w / row-y math
+   mixes `scaled(PADDING_LOGICAL)`, `scaled(LABEL_W_LOGICAL)`,
+   `scaled(RIGHT_TEXT_W_LOGICAL)` with bare `scaled(4)`, `scaled(8)`,
+   `scaled(24)`, `scaled(18)` — four un-named "small" values doing
+   semantically distinct jobs (label-bar gap, bar-text gap, header height,
+   row-1 offset). Fix: name them (`LABEL_BAR_GAP_LOGICAL`,
+   `BAR_TEXT_GAP_LOGICAL`, `HEADER_H_LOGICAL`, `HEADER_OFFSET_LOGICAL`) so
+   the row geometry is auditable in one place.
+
+5. **`src/panel.rs:340` — severity: med.** `row2_y = row1_y +
+   scale_to_dpi(BAR_HEIGHT_LOGICAL, dpi) + scale_to_dpi(ROW_GAP_LOGICAL, dpi)
+   + scaled(8)`. The trailing `+ scaled(8)` is an unexplained extra gap on
+   top of `ROW_GAP_LOGICAL`; this is exactly the inconsistency `ROW_GAP_LOGICAL`
+   was created to prevent. Fix: fold into `ROW_GAP_LOGICAL` (16) or rename
+   the extra into a labelled `ROW_TEXT_GAP_LOGICAL`.
+
+6. **`src/bubble.rs:1099, 1126` — severity: med.** `tail_right = width_px -
+   scale_to_dpi(12, dpi)` and `bar_right = (text_left - pad).max(bar_left +
+   bar_min)`. The `12` is the right-edge inset to clear the stadium's right
+   end-cap; this is conceptually `corner_radius / 2`-ish but encoded as a
+   constant that won't track if aspect ratio changes. Fix: derive from
+   `layout.corner_radius` or hoist a `TAIL_RIGHT_INSET` constant with a
+   comment tying it to the end-cap curvature.
+
+7. **`src/bubble.rs:1360-1377` and `src/tray/badge.rs:86-106` — severity:
+   med.** `build_arc` is duplicated verbatim between the bubble renderer
+   and the tray badge — same 64-segment sampling, same `FRAC_PI_2` start,
+   same edge-case `.max(1)` segment count. Fix: lift into a small
+   `geometry` / `tiny_skia_helpers` module shared by both call sites;
+   change neither call site to keep behaviour identical.
+
+8. **`src/bubble.rs:1339-1352` — severity: med.** `paint_pill` is a perfect
+   helper candidate for `panel.rs`'s bar drawing — `panel.rs` uses
+   `FillRect` rectangles with hard corners (`draw_row` lines 406-428),
+   visually inconsistent with the bubble's rounded pill caps. Fix: extract
+   `paint_pill` to a shared rendering helper module and have panel use it
+   so the two surfaces have matching bar geometry. (Cross-surface
+   consistency was the stated reason for `usage_color.rs` existing — same
+   logic applies to bar shape.)
+
+9. **`src/bubble.rs:1080-1083, 1111-1112` — severity: med.** `head_label_h`,
+   `head_pct_h`, `time_text_h`, `usage_pct_h` all add `scale_to_dpi(2, dpi)`
+   of "breathing room" to a font height, but never call it that — and the
+   computed rect height is then used by `DrawTextW` with `DT_VCENTER` so a
+   too-tight value would clip ascenders/descenders. Currently safe because
+   2 px (logical) ≈ font leading, but the magic `2` is load-bearing. Fix:
+   `const FONT_VPAD_LOGICAL: i32 = 2;` with a one-line comment "ascender/
+   descender slack for DT_VCENTER".
+
+10. **`src/bubble.rs:1141-1146, 1153-1158` — severity: low.** The vertical
+    centring expression `usage_bar_top + (usage_bar_h - usage_pct_h) / 2`
+    is computed twice for `tail_usage_pct_rect` (top + bottom). Tiny but
+    if a designer asks "where does the % text sit relative to the bar?"
+    they have to mentally simplify. Fix: compute `pct_text_top` /
+    `time_text_top` as named locals before the struct literal.
+
+11. **`src/bubble.rs:1076, 1077` — severity: low.** `big_font_px =
+    head_diameter * 26 / 100`; `small_font_px = big_font_px * 55 / 100`.
+    The 26 % and 55 % ratios are the core typographic scale of the head
+    text — promote to `BIG_FONT_RATIO_PCT`, `SMALL_TO_BIG_FONT_PCT`
+    constants with a "tweak these to retune head proportions" comment.
+
+12. **`src/bubble.rs:1078` — severity: low (dead-code adjacent).**
+    `main_font_px = small_font_px;` — `main_font_px` is identical to
+    `small_font_px` but kept as a separate field on `BubbleLayout`
+    (line 1056) and used for the countdown (line 1604, 1658). If the
+    intent is "may diverge in future", document it; otherwise drop the
+    duplicate field and use `small_font_px` directly.
+
+13. **`src/bubble.rs:1085-1096` — severity: low.** `head_label_rect` and
+    `head_pct_rect` both use `left: scale_to_dpi(4, dpi)` and `right:
+    head_diameter - scale_to_dpi(4, dpi)` — identical horizontal extents.
+    Could share a single `head_text_left`/`head_text_right` pair to make
+    "head text is centered in the head circle" structurally visible.
+
+14. **`src/bubble.rs:1216 vs 1339-1352` — severity: low.** Stadium
+    background uses inline two-circle-plus-rect path; the pill helper
+    does the same shape. The stadium could call `paint_pill(pixmap, 0.0,
+    0.0, w, h, h/2.0, bg)` and shed ~15 lines. Worth doing once
+    `paint_pill` moves to a shared module (finding 8).
+
+15. **`src/bubble.rs:1653` — severity: low (text layout).**
+    `draw_tail_text_in_rect` is called with `DT_RIGHT | DT_VCENTER |
+    DT_SINGLELINE | DT_END_ELLIPSIS`. The `DT_END_ELLIPSIS` on a
+    right-aligned 3-char string ("100%") inside a tight rect will produce
+    `1…` if the rect collapses by even a pixel — fine, but worth
+    confirming the `pct_reserve_w` (line 1103) leaves a 1-px AA safety
+    margin. Current `+ scale_to_dpi(2, dpi)` looks adequate. No fix
+    needed; flag for future locale changes.
+
+16. **`src/bubble.rs:1674-1685` — severity: low.** `draw_text_in_rect`
+    always uses `DT_NOCLIP`; `draw_tail_text_in_rect` uses
+    `DT_END_ELLIPSIS` (no `DT_NOCLIP`). The two helpers diverge silently
+    on whether text may escape its rect. Document the contract on each
+    helper ("head text trusts layout, tail text fits-or-ellipsises").
+
+17. **`src/panel.rs:447-501` — severity: low.** `draw_text` creates and
+    destroys a font on every call (4× per `paint`). Same anti-pattern in
+    `bubble.rs:paint_bubble_text` is amortised by caching `big_font`,
+    `small_font`, `main_font` for the whole paint. Not a correctness
+    issue but means the panel allocates 4 GDI fonts on every
+    InvalidateRect. Cache by `(size, bold)` keyed on the HDC.
+
+## Quick wins
+
+1. **Centralise the neutral palette** (findings 1, 2). One new module
+   `palette.rs` exposing `bg / track / time_track / time_fill / text /
+   muted` plus tray-specific tints. Replace all `Color::from_hex(...)`
+   calls in `bubble.rs:1178-1197`, `bubble.rs:1589-1598`,
+   `panel.rs:279-293`, and the byte arrays in `tray/badge.rs`. ~20-line
+   diff, kills cross-surface drift.
+
+2. **Name the padding constants in `compute_bubble_layout`** (finding 3,
+   9). Add ~6 `const` declarations at the top of the function — keeps
+   them locally scoped, matches `panel.rs` style. Designer can retune
+   metrics from one block.
+
+3. **Lift `build_arc` to a shared `tiny_skia_helpers` module** (finding
+   7). Two-file delete-and-import. Identical behaviour.
+
+4. **Promote `paint_pill` and reuse in `panel.rs` rows + stadium bg**
+   (findings 8, 14). Makes bar visual style consistent between bubble
+   and panel; bonus simplification of the stadium fill.
+
+5. **Drop / rename `main_font_px`** (finding 12). Either delete the field
+   and use `small_font_px` directly, or split the constants (`MAIN_FONT_RATIO`)
+   so future divergence is intentional.
+
+## Defer
+
+- Finding 4-6 (panel/bubble padding naming, derived `TAIL_RIGHT_INSET`):
+  worth doing alongside the palette refactor but not blocking.
+- Finding 10, 13 (local temporaries for centring math, shared
+  `head_text_*` extents): pure readability, low payoff.
+- Finding 15 (ellipsis safety margin on locale changes): keep an eye on
+  this when adding a locale wider than `999시간`.
+- Finding 17 (panel GDI font caching): only matters if the panel starts
+  refreshing more often than once per poll cycle.
+
+Out-of-scope sighting (one-line flag as instructed): `compute_bubble_layout`
+takes an `HDC` purely to measure text — couples geometry calc to a live GDI
+device. Not a render bug, but it makes the function untestable without a
+window and is worth refactoring when convenient.
+
+**Status:** DONE
+**Summary:** Renderer is functionally solid; the dominant problem is
+duplicated/un-named geometry and colour literals scattered across bubble /
+panel / badge that drift independently and resist designer-led tuning.
