 | 2026-05-13 | PR 2b shape locked via grilling: PR 6 stays separate; `<V1App />` mirrors legacy routes rendering existing page components inside v1 chrome (each phase swaps its route's component); boundary read uses `isEnabled("V1_REDESIGN")` and both branches ship in both bundles (computed-key env access skips Vite's constant-fold); `<LegacyApp />` lives at `src/LegacyApp.tsx`; v1 reuses legacy `<Footer />` as placeholder until PR 6; CSS scoped via `.v1-app` class applied both to `<html>` (via a single carve-out flag read in `main.tsx`, restoring the body-bg behavior reverted by PR 453) and to `<V1App />`'s wrapper div. | Trade-offs: convention consistency for the boundary read over per-deploy bundle separation (~5KB JS + ~11KB CSS unused per build, acceptable). The `main.tsx` carve-out exists so body bg paints against v1 surface tokens from the first paint — body itself lives outside `<V1App />`'s wrapper subtree, so the cascade only reaches body when `.v1-app` is on `<html>`. PR 8 cleanup removes both the carve-out and the App.tsx boundary read. Each Phase 2-5 PR edits `V1App.tsx`'s route table to swap in its v1 component; `LegacyApp.tsx`'s table is frozen until PR 8 deletes it.
