✅ Phase 0: Foundation (built & deployed)

Themed, multilingual, deployable shell. 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 <head> 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.
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, content MVP + case studies + /brain note pages + SEO.
