   One stylesheet for the whole app. Every class here is a CONTRACT: the 89
   module pages under modules/ already use these names, so names must not be
   renamed or removed — only restyled.

   Theming: light only. Every colour decision goes through the tokens below, so
   the palette can be retuned in one place.
