/* Page transitions (TRANSITIONS-20261026, Ariel said yes; GPT Astra team review applied).
   Native cross-page View Transitions: quick opacity crossfade, no blur, no movement (keeps the fixed header still).
   Opt-in is inline at the top of each page. Booking pages (/book/, /book/request/) opt OUT so taps never land on the overlay.
   Chrome, Edge, Safari 18.2+. Other browsers keep the normal cut. */
