- Add new racer spritesheets (8 angles × 64×64) for all 9 racers
- Introduce KART_ROT_FRAMES constant as single source of truth for rotation frame count
- Update SuperKartMode7.angleFrame(), SuperKartGame frame math, and procedural fallback
to derive from KART_ROT_FRAMES instead of magic numbers
- Update data/superkart-artwork.json with asset paths and 8-angle metadata
- Update sprites.md documentation to reflect 8-view-angle contract
Complete kart racing game featuring 12 procedurally generated tracks
across 3 cups, 9 unique racers with distinct stats, headless physics
simulation, and a secret track editor (?superkart-editor=1).
Core features:
- Mode 7 ground renderer with parallax horizon backdrops
- 12 hand-tuned tracks (speedway, beach, swamp, scrapyard, volcano, nightcity)
- 9-racer roster with balanced archetypes (all-rounder, drift pirate, etc.)
- Headless race simulation for deterministic AI and headless verification
- Item system (bolt, seeker, oil, turbo, overdrive, emp, coins)
- Position-weighted item roulette and rubber-banding
- AI opponents with skill-based driving and stuck-recovery
- Full track editor with live preview, validation, and export
- 275 verification checks covering schema, physics, AI soak, and determinism
