   STATUS COLOR SYSTEM
   Colors are defined once as root vars, then resolved via
   data-status attribute so any element can be themed the same
   way without duplicating color values across selectors.

   Usage in Twig:
       <span class="badge" data-status="{{ appointment.status.value }}">
           {{ appointment.status.label() }}
       </span>
       <tr data-status="{{ appointment.status.value }}"> … </tr>

   Usage in JS (FullCalendar events):
       el.dataset.status = event.extendedProps.status;
