A Prefer dark mode setting shows web pages in dark colors

Anthias 2026.07.0 adds a "Prefer dark mode" switch to Settings. Turn it on and the viewer shows the web pages in your playlist in dark colors, with no change to the pages themselves.

The darkening is automatic, so it also applies to pages that were never designed with a dark theme. Check how your own pages look with it on before you leave it that way.

The setting is off by default. Saving it restarts the viewer's web view, so the change shows on screen without a reboot. Images and videos aren't affected.

For developers

The setting is the prefer_dark_mode field of /api/v2/device_settings, which you can read with GET and change with PATCH. The viewer passes it to the web view as ANTHIAS_PREFER_DARK_MODE=1, which turns on Chromium's automatic dark mode (--blink-settings=forceDarkModeEnabled=true).
