/* ============================================================
   PREMIUM BOOKING CALENDAR — reusable premium component. A real
   month-grid availability calendar (open/limited/full/closed),
   day → time-slot list → confirm step, all driven by static
   JSON. Structural CSS below travels unmodified between templates;
   only the variables in the --bcal-* block should be re-skinned
   per site (colours, radius, fonts).

     — same technique as the existing 4 embeds, only this block touched.
     --bcal-limited stays its original amber: that's a functional traffic-
     light "caution" colour, not component-library branding, and this site
     has no amber token to route it through. --bcal-open/--bcal-full do map
     to the site's own green/red tokens since those already exist. */
