/* =============================================================================
   booking.css — modal shell for the Calendly booking widget
   -----------------------------------------------------------------------------
   Paired with assets/booking.js. Visual rules:
     • Backdrop is a soft, blurred dim — never pure black.
     • Panel matches the project's dark cinematic palette.
     • Inline Calendly iframe gets a transparent background so it inherits the
       panel surface; we set its theme + brand color via Calendly query params
       (booking.js builds the URL).
     • Reduced-motion users get an instant fade-in instead of a slide.

   Selector contract (mirrors booking.js):
     .booking-modal[data-open="true"]
       .booking-modal__panel        — sized container
         .booking-modal__head        — title + close button
         .booking-modal__embed       — Calendly inline-widget mount (≥520px)
         .booking-modal__fallback    — shown when Calendly fails / opt-out
