The controller now resolves the surface under the blob from the ground
collider's userData.surface (the course already tags them) and reacts:
- slip (oil/ice): steering-scrub + brake throttled ~0.1x → you luge across,
and even a grippy green blob slides (Min friction combine beats grip);
- drag (honey/mud/water): horizontal speed bleeds off (sticky/heavy feel);
- rinse (water): a small periodic paint:request-cleanse — an underwater
shortcut costs you your loadout (GDD §5.5).
The surfaces.ts framework existed but nothing in the game consumed the
behaviour tags; this wires it, per that file's own "the controller queries the
surface" contract. Added a demo oil slick (applySurface 'oil' + Min combine) on
the machine-pad centre lane. Browser-verified: on oil the blob slides ~2.7u vs
0.42u on normal ground; resting on the milk river rinsed red 56.7% → 35.7% in
2s. honey-climb and mud-antipaint left as marked ponytail TODOs. build green.

Left stick is radial-deadzone analog (magnitude preserved — gentle stick =
gentle roll) feeding the same camera-relative move vector as WASD; jump goes
through the buffered-edge path as Space. Verified headless with a stubbed
navigator.getGamepads: full/half-stick speeds, single edge jump, respawn.

Integration: blob+paint+machines composed in game.ts; cannons staged along the
racing line (muzzle 26 — default 16 undershoots course distances); plate
threshold above clean-blob mass so only painted blobs trip it (paint=weight=
machine access); belt delivers riders under the bucket (shallow catch timed to
teeter drift); arch moved to a detour lane.
Cross-lane fixes found at integration, all one class — gameplay logic living
on render-frame time, which stalls in hidden tabs:
- telegraph windup -> fixed step (gates forces/dumps)
- bucket tip/pour -> fixed step (gates the splat)
- blob group sync -> fixed step in controller (paint proximity gate reads it)
world.ts grew tick()/renderOnce() + a hidden-tab watchdog interval for this.
Assets: mesh wave 1 (4 GLBs via farm: blobbo-base, toaster, spring boot,
paint bucket) + mesh_pipeline.py with outdir scp fallback for the farm's
unregistered-remote-outputs bug.
Verified headless end-to-end via tick(): move/jump/squash, cannon hits on a
moving blob, coverage->buffs (BURN 1.6x, super at 70%), mass 1.0->1.67 with
paint, plate clean-reject + painted-trip, boot launch (peak y 3.9), belt->
bucket dump (23.6% purple), arch cleanse.
