The single biggest fidelity lever from the charrette. Core had only
three.module.min.js (no postprocessing addons), so this vendors the r170
EffectComposer/RenderPass/UnrealBloomPass/OutputPass + their shader deps into
static/vendor/three/addons/, with every `from 'three'` rewritten to the SAME
vendored three (../../three.module.min.js) so the addons share the plugin's
three instance (a CDN copy would be a second, non-interoperable module).
highway_3d wiring:
- Lazy-loads the addons only when the new `bloom` setting is on (dynamic import),
builds EffectComposer(RenderPass → UnrealBloomPass(strength .65/radius .5/
threshold .82 — high so only emissive gems + the hit flash bloom) → OutputPass).
- Render loop uses composer.render() with ACES tone-mapping when bloom is active,
else the unchanged direct ren.render() with NoToneMapping (bloom-off = today's look).
- Perf-gated: OFF in splitscreen; graceful fallback to direct render if the modules
or composer fail; composer.setSize on canvas resize; disposed on teardown.
- settings.html: "Glow bloom" toggle (default on).
Verified the import chain resolves + renders via a same-origin module-load test
(EffectComposer built + a bloom frame rendered, three r170).
Charrette status: 7/8 (only #5's early/late timing tint remains — a notedetect
verdict-field change, outside the highway).
