E baked the 6 heavy hero props to <=8k tris (c522464). Re-measured every
interior GLB-on (cache-busted to bypass the dev browser's stale HTTP cache;
production clients fetch baked directly):
- record 43.6k tris (C3 target, ~273k pre-bake), draws 322
- milkbar 38.9k tris (was 468k — the R4 over-budget flag is now CLOSED)
- all rooms <=107k tris; book is the draw-call outlier (1245 draws from ~9
bookshelf GLBs + ~600 primitive spines) — tris fine, interiors render
one-at-a-time so gate 3 unaffected; instancing spines is a future lever.
Full table in docs/LANES/LANE_C_GLB_VALIDATION.md. Round 5 complete for Lane C.
