- Create scripts/generateDayIcon.tsx for on-demand icon generation
- Route handler calls script via execSync (avoids Next.js react-dom/server restriction)
- Implement in-memory caching to minimize subprocess overhead
- Show current day (01-31) on 2-column abacus in US Central Time
- High-contrast design: blue/green beads, 2px strokes, gold border
- Document SSR pattern in .claude/CLAUDE.md for future reference
Fixes the Next.js limitation where route handlers cannot import react-dom/server
by using subprocess pattern - scripts CAN use react-dom/server, route handlers
call them via execSync and cache the results.
