Implements every recommendation from the UI/UX review of the two-bar
bubble: readability bump, faster glanceability, per-provider identity,
smarter resize curve, and a richer snap behavior set.
Readability + sizing:
- Default width 180 → 200, min 120 → 140 (Windows shell minimum legible
status-text floor is 12 px; previous breakpoint produced 11 px text)
- Discrete breakpoint table replaces the linear bar_h = h/4 formula —
140/200/280/360 widths map to (bar_h, font, row_gap) of
(12,11,4)/(16,13,6)/(20,15,8)/(24,17,10)
- Aspect tapers 3:1 → 2.8:1 → 2.6:1 as width grows so bars stay
proportionally chunky at large sizes
- Right-column width now derived from GetTextExtentPoint32W of
"100% · 23h" against the real font instead of the bar_h * 6 heuristic
Glanceability:
- ring_color_for_percent rewritten as a 4-band cliff: orange < 60,
amber 60-80, red 80-95, deep red ≥ 95 — gradient hid the 75 vs 85
difference at narrow bar widths
- Percent moved inside the bar (right-aligned with auto-contrast picked
from luminance of the underlying fill or track)
- Right column now shows only the countdown ("2h 14m"), not the
combined "X% · 2h 14m" string. i18n::format_countdown is now pub so
the bubble can request countdown-only; the panel still renders the
combined string via format_window
- "5h" / "7d" muted labels added in a new left column
- Rows whose bar is ≥ 95 % get a 15 %-red blush behind the entire row;
fill color also brightens via a slow triangle wave (TIMER_PULSE,
80 ms, only armed when at least one bar is in the alarm band)
Per-provider identity:
- 4-px vertical accent stripe at the left edge — Claude orange
(#D97757), Codex green (#10A37F) — disambiguates the two bubbles
when both are enabled. Mirrored into the expanded panel so the
identity carries across surfaces
Snap behavior:
- Corner snap: release within 32 px of a work-area corner slams the
bubble into the corner with a 12-px inset
- Taskbar-adjacency: SHAppBarMessage(ABM_GETTASKBARPOS) supplies the
taskbar rect/edge; bubble docks against the inner face with a
4-px gap on the docked edge
- Peer-Y alignment: when a second bubble exists within ±8 px on Y
at release time, the dragged bubble snaps to share its top edge
- WM_SETTINGCHANGE handler re-clamps bubbles into the new work area
when taskbar moves / auto-hides / DPI changes
Color packing:
- Direct DIB writes use rgb_to_dib (B,G,R,X memory order) instead of
into_colorref (R,G,B,X COLORREF order). Already corrected in the
previous redesign for the bar fills, but the accent stripe and blush
go through the same path now
Bubble shape changes from circle to rounded rectangle showing two stacked
horizontal bars — top: session (5h), bottom: weekly (7d) — each followed
by a right-aligned "X% · Yh Zm" string (percent + countdown).
Bubble surface:
- BubbleConfig/BubbleState carry session+weekly percents and texts (mirrors
PanelData); update_percentage renamed to update_data
- Aspect ratio fixed at 3:1; size_logical is interpreted as width with
height derived. Clamp is 120..360 (was 32..128 square)
- Hit-testing uses a rounded-rect predicate (point_in_rounded_rect) shared
with the alpha mask so paint and click area can't drift
- New rgb_to_dib helper for direct DIB writes — BI_RGB 32bpp stores B,G,R,X
in memory which is the opposite of COLORREF. The previous code wrote
COLORREF-packed u32 straight into DIB pixels; invisible while every color
was gray, but the new orange/red bar fills would have rendered blue
- bar_h capped at h/4 (range 6..18) so the text font derived from it stays
small enough that "100% · 23h" fits in right_text_w (= 6×bar_h, min 56);
the first iteration had a 19-px font in a 60-px column and ellipsized
away the countdown
- Initial session_text/weekly_text seeded with "…" so the bubble has
visible feedback during the first poll instead of two empty grey tracks
Compile + cleanup needed to make the port build at all:
- Color::from_hex added back as an infallible wrapper around parse_hex
(15 call sites in bubble.rs/panel.rs assumed the old infallible API)
- Color::to_colorref → into_colorref at 5 call sites
- GetModuleFileNameW added to the LibraryLoader import in bubble.rs
- usage::Error gains Creds(#[from] creds::Error) so `?` works in the
Anthropic and ChatGPT providers
- FlattenBoxed::flatten renamed to flatten_box — the std Option::flatten
was shadowing it and yielding Option<Box<T>> instead of Option<T>
- PanelState marked unsafe Send (HWND has *mut c_void; state is only
touched from the UI thread, Mutex is for OnceLock satisfaction)
- Crate-level #![allow(dead_code)] for in-progress port API surface
(creds, usage, update, os::dpi); unused pub-use re-exports removed
App wiring:
- propagate_to_ui now feeds both windows + their formatted texts into
update_data (was a single percent)
