/* ════════════════════════════════════════════════
   CBv2 – Mobile-First Stundenplan-Formular
   Shared stylesheet — reached from the suite via the shared/ junction.

   Every colour goes through the --cbtt-* design tokens (core/design/
   design_tokens.php, markdowns/plugin/DESIGN-SYSTEM.md) so this form matches
   the classic grid (assets/css/frontend.css) and the rest of the suite under
   the active design. Fallback convention for THIS file: exactly one literal
   per token, always the Solver-Blue palette value — the fallbacks are what
   renders under the 'theme' preset (no palette printed) and on a third-party
   theme, so a second value for the same token would show up as two different
   blues on one page. Slot states use the grid's own tokens (--cbtt-available,
   --cbtt-preferred, --cbtt-possible*), never the status families: status
   colours mark status, not categories.
