UPLOAD INSTRUCTIONS

1. Upload everything inside the dustbin folder to:
   public_html/dustbin/

2. ESP32 endpoint is:
   https://flamingorovers.lance.co.ke/dustbin/api/update_bin.php

3. Dashboard is:
   https://flamingorovers.lance.co.ke/dustbin/

4. If the dashboard says API error or data is not saved, set folder permission for:
   dustbin/api/
   so PHP can create latest_bin_data.json. Usually 755 works, sometimes cPanel may need 775.
