+- **Visual-regression harness now renders deterministically.** The four
+  `examples/whynot-control` pages render and screenshot cleanly against the new tokens.
+  Snapshot baselines are now **gitignored** (generated locally via
+  `pnpm test:visual:update`, not committed — they are large binary test artifacts).
+  Along the way:
   - `serve.json` (`cleanUrls:false`) — the static server was 301-redirecting
     `/…/index.html` to a trailing-slash-stripped URL, shifting the document base and
     404'ing every relative asset (also broke `pnpm showcase` in the browser).
