/**
 * KAT Booking popup — WhatsApp + Telegram, calendar, assistant, map.
 * Mobile-first + smart responsive (phone bottom-sheet -> tablet/desktop card).
 * Scoped under .kat-book so it never leaks into the host theme.
 *
 * v4 redesign: sectioned "When / Details / Confirm" flow, chip-based time
 * grid, party-size stepper, seating preference, and a dedicated success
 * screen — layered on the same data-kat-book-* JS hooks.
