/* Bookings, student side: /book/<brand>/, /book/<brand>/<offering>/, the card
   on the brand page, /bookings/, /b/<token> and /v/<code>.

   Built on the shop's vocabulary (shop.css: the stall, shop-card, pdp, slip,
   pay-panel, paid-form, timeline, status-tag, qty-stepper), so a booking reads
   as part of the same site. Only what bookings add lives here: the request
   form, the date and seat pickers, the thread, the quote, the voucher. Light
   first; every colour is a token, so dark follows from [data-theme="dark"]. */
