/* Public-holiday all-day marks. Advisory = subtle solid band; closed = striped/hatched so a
   company-wide shutdown is unmistakable. Applied to FullCalendar events via className.

   The label colour MUST be set on `.fc-event-main` (not just `.fc-event`): FullCalendar v6 puts
   the event text colour on `.fc-h-event .fc-event-main` (default white), which out-specifies a
   `color` on `.fc-event.<class>` — so a plain `.fc-event.holiday-advisory { color }` left the
   label white on the light band. Targeting `.fc-event-main` (specificity 0,3,0) wins and gives
   the dark, theme-aware emphasis colour. */
