/* ===========================================================================
   Validation UI — queue, read-only version browser, decision sheet.

   Tokens are used WITHOUT fallbacks on purpose: a fallback hides a typo, and an
   invented token then renders the fallback forever and never picks up dark mode
   or any of the eight themes. Bare var() fails visibly instead.

   --qz-text (NOT --qz-ink): ink is the mascot's constant visor colour and has no
   dark-theme override, which is exactly how a previous surface shipped with
   invisible titles in dark mode.
