- PiP: sized in _resize (~24% w, 16:9, bottom-right) — CSS aspect-ratio is
unreliable on <canvas> and had ballooned it. Click-to-swap main<->active cam;
_render(cam,canvas) restores aspect after a pip blit so swap never distorts.
renderActiveCamera/pause/resume contract unchanged (M3 finalRender safe).
- room3d: SpecGlossPlugin on GLTFLoader — CC/Reallusion GLBs use
KHR_materials_pbrSpecularGlossiness (dropped in three r160) and rendered
flat white; map spec-gloss -> MeshStandard. lady.glb now withMap=26/26.
Verified live at :8020, zero console errors.
