Implement `will-change` hints strategically + - Meet or beat current bundle budgets (3MB total, 1.5MB assets) + +### Stage 7: DEPLOYMENT & MONITORING +- **Touchpoints:** OpenNext build, Cloudflare Workers (via Wrangler), D1 database, R2 assets, production users +- **Actions:** Staged rollout, monitoring errors, gathering feedback +- **Emotions:** ๐Ÿคž Hopeful โ†’ ๐Ÿ‘€ Vigilant โ†’ ๐Ÿ˜… Relief when stable +- **Pain Points:** + - **OpenNext SSR/SSG build** with new CSS bundle size + - Cloudflare Workers cold start performance with larger static assets + - Workers runtime limits (CPU time, memory) with new animation JS + - Users on slow connections see FOUC (flash of unstyled content) + - Mobile users with motion sensitivity need `prefers-reduced-motion` support +- **Opportunities:** + - Use OpenNext static optimization for critical CSS inlining + - Leverage Wrangler preview for testing before production deploy + - Edge caching strategies for new design assets on R2 + - Analytics to track user engagement with new design + +**Deployment Commands:** +- Build: `npm run pages:build` (OpenNext compilation) +- Preview: `npm run preview` (OpenNext local preview) +- Deploy: `npm run deploy` (Wrangler deploys to Cloudflare Workers) + +### Key Insights from Journey Map + +**Critical Success Factors:** +1. **Parallel CSS System** -
