HarryHighPants/esp32-git-contributions-epd ? reverse-engineered prompt

Build me an ESP32 powered e ink display that shows my GitHub contribution graph and commit streaks in a clean, readable way.

I want it to wake up, connect to Wi Fi, pull my contribution data, and refresh the screen every few hours without draining the battery too fast. If the Wi Fi or data fetch fails, show a clear error icon on the display instead of just freezing. Also add a simple setup mode I can enter by holding a button, where the device creates its own network and opens a browser page so I can enter my Wi Fi details and configuration from my phone.

Please include a dark mode option too, since this is meant to sit on a desk or shelf. Use the ESP32 and the LilyGO style e ink display setup, and make it easy to flash and tweak in PlatformIO. If you need to look up current docs for the display or ESP32 libraries, go ahead.
