Summary
docs/esp32-guide.mdcovering ESP32-specific challenges when using the Hello Club APIContext
Based on real problems solved in a production ESP32 badminton court timer that polls Hello Club for event bookings. The ESP32 has ~60KB usable RAM, and a single TLS connection uses ~45KB — making HTTPS API calls uniquely challenging on this platform.
