Lane A: blob controller, feel layer, follow camera, greybox
- src/blob/createBlob.ts: rotation-locked dynamic ball + clean UV-sphere body mesh (untouched UVs for Lane B) + cosmetic eyes; implements frozen Blob. - src/blob/controller.ts: fixed-step System. Camera-relative WASD via impulses, buffered+coyote jump, grounded raycast, emits blob:jumped/blob:landed. Reads blob.modifiers every frame: speedMul, jumpMul, massMul, grip, size. - src/blob/feel.ts: the comedy engine. Underdamped springs for landing squash, jump stretch, inertial jelly lean, idle breathing + run bob; base-pivoted so squash plants on the floor. Driven by the frozen wire events. glow -> emissive. - src/blob/camera.ts: soft-follow third-person cam with position lag, yaw ease behind travel, and FOV kick at speed. - src/course/greybox.ts: Breakfast Rush greybox — start plateau, ramp, gap jump, slope, translucent milk river (surface:water), machine drop area, finish pad. - src/demo/lane-a.ts: boots world+greybox+blob, HUD + once/sec state log, debug keys 1/2/3 (speed/jump/size) plus 4/5/6 (mass/grip/glow), 0 reset, R respawn. npm run build passes (tsc strict + vite). Owned paths only. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
