/* ============================================================
   Theme switch — the light / dark / system segmented control.

   Standalone on purpose: it is shown on the three staff portals (which run on
   the phoenix tokens) and on the staff login (which runs on the public
   --color-* tokens). Every colour resolves through a chain that ends in a
   literal, so the control looks right on either stack and on a page that
   defines neither.
