Player-triggered contraptions that chain purely via world.events
('machine:signal') with a mandatory ~0.5s telegraph before any force or
paint dump (GDD readable-chaos pillar).
src/machine/:
- telegraph.ts: unmissable windup (accelerating flash + shake + scale pulse)
ticked once per world; parts await it and only then fire.
- parts.ts: PressurePlate (real body.mass() threshold), SpringBoot
(telegraph -> impulse on strike volume), SeeSaw (Rapier revolute joint
with limits + optional rest tilt), BucketDump (telegraph teeter ->
paint:request-splat + slosh), ConveyorBelt, BubbleArch (rising-edge
paint:request-cleanse + bubbles), Fan (per-step impulse so mass does the
work). Config-driven; no cross-instance references.
- surfaces.ts: normal/ice/oil/honey/mud/water registry with applySurface +
surfaceAt (downward ray) query.
demos/lane-c.html + src/demo/lane-c.ts: heavy ball runs
PressurePlate -> SpringBoot -> SeeSaw -> ice runway -> BucketDump, plus
conveyor/arch/fan and ice/honey probe lanes. Debug keys T/L/S/F/P and
per-second STATE console lines. Layout constants tuned via a headless
physics sweep so the chain completes deterministically.

Fixed-step world runtime, event bus wire protocol between lanes, integration
seam (game.ts) with placeholder ball. Lanes A/B/C own disjoint dirs.

GDD.md is the review artifact: feature tiers, draft 7-colour buff table,
tech recommendation (web-first three.js+Rapier), milestones, Opus 4.8 lanes.
