Built with Fable, deployed to Vercel. **Shipped:** - Astro 5 + React 19 islands + Tailwind 4 + TS; `@astrojs/vercel`; Speed Insights. - Stone tokens for both themes; no-flash inline `` theme script (localStorage → prefers-color-scheme), persisted toggle, no-JS OS fallback. - All 7 locales route with correct `lang`/`dir`. Urdu mirrors fully (Nastaliq extra line-height so it doesn't clip). - **Per-locale fonts verified:** built HTML has zero Noto refs on `en`/`hi-latn`; each script locale preloads only its own font. General Sans (38 KB) + Inter latin subset (48 KB) self-hosted, preloaded, `swap`. - JS budget: only ThemeToggle (~1 KB) + LanguageSwitcher (~1.3 KB) hydrate (+ shared React runtime 58 KB gz, async). Rest static. **Lighthouse:** en 99/100/96/100 · ur 92/100/96/100. BP 96 = Speed Insights 404 on localhost (100 on Vercel). Urdu perf 92 = 233 KB Nastaliq font on emulated mobile → subset further in a later phase. **Judgment calls:** - AA fix: light `--muted` #726D65 (4.28:1) → **#6D6961** (4.55:1). See [D011 - Colour Direction Stone](/brain/d011-colour-direction-stone/). - Deploy gotcha: parent `~/Developer/Workspace/vercel.json` (salutebutton) was hijacking `vercel link`; project got its own `vercel.json` + `.vercel` (salutebutton's file untouched). **Deferred TODOs (before launch):** set real domain in `astro.config.mjs` `SITE` (drives canonical/hreflang); replace footer social placeholders + contact email (use `saifmd238@gmail.com` per spec, not the work email Fable stubbed). Next: [Phase 1](/brain/roadmap/), content MVP + case studies + `/brain` note pages + SEO. ## Linked from - [D011 - Colour Direction Stone](/brain/d011-colour-direction-stone/) - [D015 - Defer Content Translation](/brain/d015-defer-content-translation/) - [Roadmap](/brain/roadmap/) All notes: [/brain/](/brain/) --- Mohd Saif, Product Engineer.
