- Introduce soundtrack override system allowing games to define custom music
- Add Nintendo-themed soundtrack for Super Kart (2 tracks with metadata)
- Make main menu track configurable via data/music.json instead of hardcoded
- Add MusicPlayer volume parameter for per-soundtrack volume control
- Lazy-load per-game audio assets via assetManifest on game entry
- Add SPACE/X keyboard shortcuts to advance Super Kart menus
- Play kart-spinner SFX when player picks up an item in Super Kart
- Increase speech queue volume to 1.0
- Add Super Kart icons artwork and additional music assets
- Super Kart: populate missing theme image paths, increase acceleration spread,
and add a track loading panel to the editor
- Civilization: display completion notifications for spaceship parts with
direct navigation to the building city
- Profile: implement export/import via .fcg files with validation, download,
and restore flows
- UI: add multi-button modal support, improve ProfileScene layout with avatar
masking and info card, and rename Arcade category to "Video Games"
- Add Coinage (1 shield → 1 gold) and Public Works (2 shields → 1 food)
special build options for cities, with remainder carry logic in shieldBox
- Update AI to fall back to producing gold or food instead of stockpiling
redundant defenders when nothing else is available
- Fix mid-build detection to check build.type before comparing shield progress
- Add City Screen UI for special builds: display gain per turn, color-coded
rows, and tooltips
- Only apply class-switch penalty when switching between unit/building
production types
- Add verification tests for coinage payout, public works remainder carry,
and AI special build fallback
feat(superkart): fix player kart scale + add missing backdrop images
- Compute PLAYER_KART_SCALE from MODE7 parameters instead of hardcoding,
keeping player and AI karts consistent at the camera's follow distance
- Wire up previously null backdrops: volcano, scrapyard, swamp, speedway,
nightcity
- Add beach theme artwork and register paths in artwork JSON
- Implement AI rubber-banding that scales AI top speed based on gap to player
- Configure engine classes with varying rubber-band strength (Cruiser most forgiving, Turbo least)
- Balance racer stats: boost Kona top speed, reduce heavy racer accel/handling
- Update verification script to validate new rubber-banding configuration
- 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:

- 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
