Device-specific note

This project is tuned for the M5Stack Paper S3 and its display size, rotation, and power behavior. Running it on another e-ink display usually requires extra configuration (display driver/init, resolution/layout coordinates, update behavior, and sleep/power handling) before it will render correctly.
