Egress optimization: - Add s-maxage + stale-while-revalidate to all API endpoints for Vercel CDN caching - Add vercel.json with immutable caching for hashed assets - Add gzip compression to sidecar responses >1KB - Add gzip to Railway RSS responses (4 paths previously uncompressed) - Increase polling intervals: markets/crypto 60s→120s, ETF/macro/stablecoins 60s→180s - Remove hardcoded Railway URL from theater-posture.js (now env-var only) PWA / Service Worker: - Add vite-plugin-pwa with autoUpdate strategy - Cache map tiles (CacheFirst), fonts (StaleWhileRevalidate), static assets - NetworkOnly for all /api/* routes (real-time data must be fresh) - Manual SW registration (web only, skip Tauri) - Add offline fallback page - Replace manual manifest with plugin-generated manifest Polymarket fix: - Route dev proxy through production Vercel (bypasses JA3 blocking) - Add 4th fallback tier: production URL as absolute fallback Desktop/Sidecar: - Dual-backend cache (_upstash-cache.js): Redis cloud + in-memory+file desktop - Settings window OK/Cancel redesign - Runtime config and secret injection improvements
