FULLSCREEN

• Full codebase refactor — CSS design system (tokens, components, screens, animations), 12 UI modules extracted from main.js, game subsystem decomposition
• Online latency reduced ~30ms — 20Hz netcode (was 15Hz), 50ms interpolation buffer (was 80ms)

• Fixed matchmaking race condition — failed createMatch now detects if opponent already matched you
• Fixed queue presence ordering — presence written before queue doc to prevent stale pruning
• Match callbacks registered before entering queue to prevent missed instant matches
• Playlist drag reorder no longer garbles play order — shuffle indices remapped instead of re-randomized

• signalLoaded retry on failure, listener setup before write to prevent race conditions

• ANNIHILATED the 0 FPS death lag — hunted down a brutal Three.js shader recompilation bug where hiding the player group nuked every light from the scene graph, forcing the GPU to recompile every single MeshStandardMaterial shader in the entire arena on the death frame. Deaths are now buttery smooth, zero stutter, zero mercy
• SpotLight headlight beam now properly managed — was created but never returned from bike builder, making it impossible to zero on death. Dragged it out of the shadows and gave it a proper killswitch
• Trail vibration segments no longer haunt you from beyond the grave — glowing wall segments that were vibrating near the player now properly reset when the bike dies, instead of frozen mid-jiggle for eternity
