The theme picker shows NORD, MOCHA and LATTE. Nord is the base theme
in the CSS, the browser bar color and the PWA manifest. The startup
script applies the theme before the first paint.
A device that saved Mocha changes to Nord one time. After that, a user
can select Mocha again and the app keeps it.
The Nord red #bf616a has only 3.05:1 contrast on the background, so the
danger color is the lighter #dc8890 (4.74:1).
