* chore: add gstack skill routing rules to CLAUDE.md
Append a "## Skill routing" section so future Claude Code sessions in this repo route
each task through the matching gstack skill (e.g., /investigate for bugs, /ship for PRs,
/office-hours for product brainstorming).

* chore: scaffold Astro 5 + TypeScript strict with base /try-gstack/
Initialize the project per the autoplan-locked decisions:
- Astro 5 SSG, output static, base path /try-gstack/ for GitHub Pages subdirectory hosting
- TypeScript strict (Astro's strict tsconfig + path alias ~/* -> src/*)
- @astrojs/sitemap for SEO meta
- bun as the package manager (lockfile committed)

* feat: Vietnamese landing page with Be Vietnam Pro + i18n stub
Implement the locked design decisions D2 (typography) and D3 (palette) plus the i18n
discipline from autoplan eng review:
- Be Vietnam Pro single family (woff2, weights 400/500/700, vietnamese subset) self-hosted
via @fontsource so KaTeX/CDN-blocking ISPs cannot break the page
- font-feature-settings: "kern", "locl" for proper VN diacritic positioning
- 17px body / 1.6 line-height / max-w-prose 56ch (denser than English)
- 3-color SGK-aligned palette in tailwind config: pair1 #D7263D, pair2 #1B998B, pair3 #F46036
- BaseLayout with lang="vi", canonical URL, OpenGraph (vi_VN), X-Frame-Options DENY
- src/i18n/vi.ts holds every user-facing string; t() helper resolves the active locale.
Adding English later means adding en.ts; no string churn through templates.
- Landing page lists three grade cards with "Sắp ra mắt" status (modules ship later)

* test: bootstrap Vitest with pure geom-engine vec module
Establish the math-engine boundary and test discipline from autoplan eng decision E2:
- src/geom-engine/ is pure (no DOM imports allowed); first module is vec.ts
- Vec2 helpers: vec, add, sub, scale, dot, len, dist, normalize, approxEqualLen
- EPSILON_LEN=0.5 viewBox units justified vs ~4px human drag precision
- scale() normalizes IEEE-754 -0 back to +0 so consumers don't see signed-zero ghosts
- Vitest config gates the module at 95% line/function/statement, 90% branch
- 16 unit tests covering commutativity, mutation safety, orthogonality, normalization,
and EPSILON tolerance behavior
Property tests via fast-check come with the first canvas module; this commit establishes
the test scaffold so adding them later is one dependency away.

* ci: GitHub Actions test workflow + Pages deploy via deploy-pages@v4
Wire the autoplan-locked CI/CD pipeline (decision E3) for GitHub Pages hosting:
- ci.yml: typecheck + tests + build on every PR and push to main
- deploy.yml: build + actions/deploy-pages@v4 on push to main, concurrency-grouped
so a force-push retry doesn't abort an in-flight rollback
- Build env pins SITE_URL=https://tiennm99.github.io and SITE_BASE=/try-gstack so
astro.config.mjs produces correct canonical/OG URLs against the subdirectory host
- bun 1.3.13 pinned for both workflows
Lighthouse-CI + size-limit gates deferred until the first canvas module ships
(no JS bundle to budget yet — current pages are zero-JS).

* chore: VERSION 0.0.1.0 + CHANGELOG + RUNBOOK + README rewrite
Initial 4-digit gstack version (matches package.json), changelog entry for the scaffold,
operations runbook covering rollback and the deferred .vn domain trigger (500 sessions/30d
OR 1 organic teacher share OR 5+ modules shipped). README rewritten as the project README
for Hình Học Sống with the locked architectural decisions visible to teammates.

* chore: TODOS.md tracking deferred autoplan items
Capture the deferred work surfaced by the /office-hours + /autoplan reviews so the
backlog is visible to teammates and bisectable from the source-of-truth design doc.
Organized by component (Phase 0 distribution, TheoremCanvas, Module 3/1/2, testing
infrastructure, retention, domain) then priority P0–P4. Per the gstack TODOS.md
format conventions.
