+"""Generic ESP32 board driver (custom firmware).

+This is a template driver for custom ESP32 firmware.
+Copy this folder, rename it, and implement the HTTP endpoints
+to match your own firmware's API.
+
+Expected firmware endpoints (same shape as Olimex by default):
+    POST /relay/on?relay=<n>
+    POST /relay/off?relay=<n>
+    POST /relay/toggle?relay=<n>
+    GET  /relay/status?relay=<n>   → {"state": <bool>}
+    GET  /input/status?input=<n>   → {"state": <bool>}
+    POST /register?callback_url=<url>
