5x follow-up: WebGL scene-correctness + FPS verifier (closes the biggest coverage gap)

scripts/verify-scene-render.mjs (npm run verify-scene-render) asserts the Three.js scene actually
renders the wallcoverings — not just 'canvas drew something': 50 wing boards in the arc, 639 meshes
/227 textured (maps loaded), centre book present + book-matched (L mirrored/R normal), renderer
draw calls>0, frame loop alive. FPS measured avg 72 headless Chrome (>=55 spec target; real hw higher),
0 console errors. Closes the contrarian's #3 (24KB screenshot proves nothing) + the Age View Phase-5.1 FPS gate.

-## Honest coverage boundary (NOT verified by this /5x run — do not assume fine)
-The six-way suite + these probes do NOT cover, and I am not claiming correctness for:
-- WebGL **scene correctness** (a 23–24KB screenshot only proves the canvas drew *something*, not that boards/
-  patterns/room render right).
-- **FPS** budget (≥55fps) — Age View Phase-5.1 FPS gate still unrun.
-- **Mobile**/touch layout, and the behavioral features in recent commits (At-the-Table seated view,
-  consultation-nook group/hide, board-flip animation) — no automated coverage.
-The Age View senior APCA/type gate IS covered separately (`npm run verify-ageview-gate`, all 10 bands pass).
+## Coverage boundary (updated)
+NOW COVERED by committed verifiers:
+- WebGL scene correctness + FPS `npm run verify-scene-render` — asserts 50 wing boards, 639 meshes/227 textured, book-matched centre book, draw calls>0, live loop; measured avg 72fps headless (>=55 target).
+- Age View senior APCA/type gate `npm run verify-ageview-gate` — 10/10 bands pass.
+- Sort+density localStorage persistence `npm run verify-sort-density-persist` — survives reload.
+STILL NOT COVERED (do not assume fine): mobile/touch layout; the behavioral features in recent commits (At-the-Table seated view, consultation-nook group/hide, board-flip animation, add/drag/remove samples).
