- lighting.js sets scene.environment (neutral PMREM sky->ground gradient, no asset) in attachRenderer, before CitizenSim constructs; Lane D rig-fleet peds bake their impostor atlas from it and render dark if null. Verified set in street/night/interior + after interior-return.
- Re-measured worst continuous-walk view WITH citizens (pop 140, 125 active peds) via window.DBG: 263 scene / 275 total midday, 275 night -- <=300 everywhere. Radius-2 auto already the spawn default.
- Round-3 task 3 (furniture GLB footprints) standby: Fable s3.4 manifest upgrade not yet landed.
- Docs: LANE_B_NOTES.md + B-progress.md round-3 updates.
