- 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.
