1. React.memo on WindowRenderer — prevents re-renders when parent state changes but no windows are affected 2. Coordinate display via direct DOM ref — no React state updates on mouse move (was triggering re-renders on every pixel) 3. useDeferredValue for sidebar vitals + player list — React prioritizes map interactions over stat text updates 4. Chat messages in ref — stores in useRef instead of useState, only bumps a version counter for re-render. Eliminates a new Map() allocation on every chat message. 5. Lazy-load 8 window components — InventoryWindow, CharacterWindow, RadarWindow, CombatStatsWindow, IssuesWindow, VitalSharingWindow, StatsWindow, CombatPickerWindow all loaded on first open. Main bundle dropped from 278KB to 211KB (24% reduction). 6. Preload critical assets — dereth.png, backpack icon, dungeon_tiles.json via <link rel="preload"> in index.html for instant map render. 7. Bundle splitting — React runtime extracted to separate 12KB chunk (cached independently). Window components split into 8 chunks. Total: 13 chunks vs previous 2. 8. Service worker — caches map images, icon sprites, and dungeon tiles. Icon images cached on first fetch. Repeat page loads serve from cache instantly. Auto-cleans old cache versions. Net result: - Initial load: 211KB main + 17KB CSS (was 278KB + 17KB) - React cached separately: 12KB - Windows load on demand: 1-15KB each - Dashboard with Recharts: 425KB (unchanged, still lazy) - Map images/icons: cached by service worker after first load Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
