/* ============================================================
   Our booking calendar (js/booking.js) on /book-discovery, /breakdown/resources and
   /forecast/reveal. The same look as the Installer MOT's booking step (css/mot.css,
   .mot-bk-*): a dark glass card, asked as three steps (day, time, details). GHL still
   holds the availability and the booking (api/book.js). Colours from style.css tokens.
