 - v1.2 roadmap: ThemeToggle via DOM class toggle, not React Context (avoids re-render cascade)
 - [Phase 08-01]: Two-layer CSS token pattern: @theme var() references + @layer base :root/.dark raw values — required for .dark cascade in Tailwind v4
 - [Phase 08-01]: vi.stubGlobal for localStorage/matchMedia in tests — Node v25 experimental WebStorage breaks standard Storage API in jsdom environment
+- [Phase 08-02]: Mechanical migration only — zero DOM structure changes, only className strings replaced
+- [Phase 08-02]: Post-migration grep check is mandatory — replace_all can miss occurrences in dual-branch components with identical className strings
