Fixes: - #22 OrbitControls damping: call updateControls() in animate loop - #23 Empty catch blocks: add console.warn + error surfacing to chat panel - #24 escapeHtml: add quote escaping (" '), use in renderAgentList - #25 WS reconnect: check close code (1000/1001) before reconnecting, add exponential backoff + heartbeat zombie detection - #26 IDLE state visibility: brighten from near-invisible to #005500 - #5 PWA: manifest.json, service worker (network-first), theme-color, favicon, loading screen, safe-area-inset padding, apple-mobile-web-app - #14 Adaptive render quality: new quality.js hardware detection (low/ medium/high tiers), tiered particle counts, grid density, antialias, pixel ratio caps New files: - js/quality.js — hardware detection + quality tier logic - manifest.json — PWA manifest - public/sw.js — service worker (network-first with offline cache) - public/favicon.svg — SVG favicon - icons/icon-192.svg, icons/icon-512.svg — PWA icons
