/*
 * Booking UI. Spec 11.3 for the grid states, 13.1 for RTL, 13.3 for focus.
 *
 * Two rules that are not style preferences:
 *  1. Logical properties only. No margin-left, no padding-right, no left/right.
 *     The Dari site is RTL and physical properties silently break it.
 *  2. Colour is never the only signal. Every state pairs a fill with a border and
 *     a word, so it survives colour blindness and a bad phone screen in sunlight.
 *
 * Tokens come from the theme. Fallbacks are here so the plugin still looks
 * deliberate if it is ever activated on another theme.
