/* book.css — the hosted booking page.
 *
 * Built on the shared foundation (mg-ui.css): every colour, radius, space,
 * duration and focus ring comes from its tokens, so the page follows the
 * visitor's light or dark preference with no palette of its own. The only
 * colour a business brings is its accent (--bk-accent), used as a FILL with
 * text computed to be readable on it (--bk-on-accent) -- never as text.
 *
 * The one memorable element is the work-order slip: a dispatch ticket that
 * fills in as the customer chooses, and is stamped when the booking lands.
 * Everything else stays quiet.
