/* Dark mode — set by clicking the sun/moon button in the top nav (includes/theme.php flips a
   cookie and reloads the current page; the server renders the right theme immediately, so
   there's no flash of the wrong theme and no client-side JS involved).
   Every color above is a variable, so this block is the whole theme: it re-points the same
   variables to darker values rather than duplicating every rule. Stage/status colors are
   brightened a little so they still read clearly against a dark background, and the tint
   backgrounds behind pills/alerts become soft translucent versions of their own color instead
