js/kitthumbs.js renders each kit GLB to a 128x96 sprite once (offscreen
renderer, framed by bounding sphere), POSTs to /api/kit-thumb, and all 52
are committed under assets/kit_thumbs/ so every checkout gets instant thumbs;
the generator only runs for props without one (future kit drops). KIT drawer
shows them with category groups and filter.
js/colliders.js derives world-space colliders from kit manifest hints +
a table for builtin props (bins, planters, trunks, fences...). Test ride
resolves circle-vs-box/circle push-out — you scrub and stop instead of
riding through furniture. Exports gain an additive COLLIDERS array for
bookquoy to adopt when its player is ready; existing contract untouched.

serve.py mounts ../park_kit at /kit/. New PARK KIT drawer browses all 52
manifest props (filter + category groups); placing one creates a linked unit:
textured GLB + matching heightfield element (anchored on the coping/grind
line; quarter kind gained an optional h cap for truncated real-mini-ramp
transitions) + grindable edge rails. Move/rotate/scale/delete cascades through
the links. Kit textures also drive the ground: park.surf {slab,grass} pattern-
fills the bake (concrete_green, tarmac, grass_dry...), PARK panel selects.

js/grass.js: reusable single-file grass module for all our games — GPU-instanced
blades (33k+ in one draw call), vertex-shader wind hashed per blade, root->tip
fake-AO gradient x per-instance tint, alpha-test pixel style (nearest-filter
16x24 canvas cards, stepped sway), deterministic seed, player-push uniform.
docs/GRASS.md records the technique ladder (clump maps, shell texturing,
billboard LOD, MB atlas gen) for future tiers. Auto-grows on parkland + islands,
PARK panel style/density, included in exported levels via buildParkScene.
Test ride: grind physics — falling onto any flattened steel (rails, ledge caps,
pool coping) locks a slide along the segment, pop off with Space or ride off the
end; grass parts around the rider.

New bowlpoly element: the rim is a polygon, every vertex a draggable handle
with its own depth slider. Inside/outside corners, hips, shallow-to-deep
escalators and waterfall drops all come from the same continuous carve (IDW
floor blend, quarter-pipe wall transition) — no seams by construction. Auto
pool coping (bullnose tube, exported as grindable ledge segments per rim
edge) and tile band baked into the ground texture. Ships parks/pool_demo.json
(THE POOLROOM) as a premade showcase; ridden end-to-end in test mode.

New heightfield kinds: hip/corner quarter, kicker (tunable concavity), roller,
wedge/manny pad, volcano, round-bowl option, quarter vert extension. Rails are
now polylines (kink/dbl-kink/rainbow/A-frame/pole-jam/donkey presets, round or
square profile, per-node drag handles) that flatten to straight segments on
export so bookquoy grind detection is untouched. 13 parametric street props
(jersey barrier, picnic table, parking block, fence, floodlight, bleachers...).
Palette regrouped TRANSITION/STREET/STEEL/PROPS; park check covers new kinds.

Data-driven parks: one heightAt(x,z) evaluated from element JSON drives the
editor viewport, collision, test ride, and exported game levels. Ships with
Paddo ported from bookquoy, a MODELBEAST panel (gen images, cut bg, image->3D,
place farm GLBs as props), image decals + reference underlay tracing, a park
design linter (docs/DESIGN_PRINCIPLES.md), THPS-style instant test ride, and
a level.js codegen that drops straight into bookquoy.
