Add secrets to build step in deploy.yaml:
- NEXT_PUBLIC_API_BASE
- SERVER_ID
- ACCESS_TOKEN
These are baked into static export during build, not needed by Cloudflare.
- Create Next.js app with TypeScript, Tailwind, and Postcss
- Extract API logic, types, and utilities to lib/
- Build React components for Race Results, Driver Standings, Points Key, and D3 Chart
- Use environment variables for API credentials (NEXT_PUBLIC_*)
- Static export (output: 'export') for Cloudflare Pages deployment
- D3 chart rendered client-side with dynamic import
- Update deploy workflow to build and deploy ./out directory
- Remove original public/index.html
