- Generate 60 levels across 5 themed tiers (Downtown, Freight Yard, Airport Apron,
Construction, Night City) with guaranteed minimal and unsolved board states
- Rewrite generator (tools/genRushHour.js) with refine() pipeline that strips
redundant vehicles and re-hardens boards, plus hill-climbing phase B
- Add comprehensive verifier (tools/verifyRushHour.js) checking solver correctness,
structural criteria, MINIMAL/UNSOLVED properties, and curriculum shape
- Implement procedural vehicle art (RushHourArt.js) with baked textures, per-theme
decals (hazard, hivis, freight, neon), and themed board surfaces
- Move level bank to assets/gamedata/rushhour/levels.json and fetch on entry
instead of preloading at boot
- Restructure level JSON with tiers, level names, par, and difficulty metrics
(decoyDensity, targetRetreats, firstMoveFanout, carsMoved)
- Update level select to display tiers with themed swatches and color-coded labels
- Show level name and theme in HUD during gameplay
- Tighten hint solver with maxStates budget to prevent main-thread stalls
- Update PreloadScene to remove rushhour.json from boot-time assets
