/* ═══════════════════════════════════════════════════════════════
   D4 — Google Calendar booking modal — Variant "C — Halo Command Modal"
   (client-approved)
   Ported from design-variants/D4-google-calendar.html: the shared
   (non-gated) calendar-engine styles it depends on (.d4-cal-*,
   .d4-slots/.d4-slot, .d4-field, .d4-confirm-btn, .d4-success*,
   .d4-microhint, .d4-placeholder) plus the [data-variant="c"]-gated
   halo modal skin, with the ancestor prefix stripped since this page
   only ever uses variant C.

   Availability is loaded from the same-origin PHP backend. Google
   credentials and Calendar IDs never reach the browser.

   Reuses existing tokens from premium.css :root — no new colors.
