Switching between light and dark mode

Open the menu button at the top right. The theme switch and language selector are both there.

Your choice is remembered on that device. Changing it on your phone does not change it on your computer, since the setting is stored locally rather than on your account.

Language

The site supports a wide range of languages. Translation applies to the interface and to most content. Where a translation is unavailable, the original English is shown rather than an unreliable machine version.
