- Panel is mounted sideways: render landscape (600x400), rotate to the panel's native portrait orientation right before writing to hardware. - Web UI: card-based layout, dark mode, active nav highlighting, save confirmation toasts, error banners. - Rotation: separate enabled/disabled toggle (off pins to the first screen in the list) and the interval is now in minutes instead of raw seconds. Migrates existing config.json from the old interval_seconds field. - Weather: type a city name instead of hunting down coordinates, resolved via Open-Meteo's free geocoding API. Manual lat/long still available as a fallback.

"""Driver for the Waveshare epd4in0e (4", 6-color Spectra) panel.
|
|
|
|
Thin wrapper around the vendored `waveshare_epd.epd4in0e` module -- the exact
|
|
driver already proven working under the InkyPi install on this Pi. That
|
|
driver only exposes `Clear()` and `display()`, both of which do a full
|
|
`TurnOnDisplay()` flash cycle; there is no partial-refresh path for this
|
|
panel at the hardware/SDK level, confirmed by reading the driver itself.
