/*
 * R&A Booking Widget - booking.css
 *
 * Design tokens resolve against the Client Center's brand.css (the single
 * source of truth for R&A brand values). Each alias below reads the canonical
 * variable and falls back to its literal value, so this file renders correctly
 * whether or not brand.css is loaded - and automatically follows any future
 * brand.css change when it is.
 *
 * Canonical tokens: --accent #8e191c, --text #181818, --border #e7e3dd,
 * --r 10px, --font 'Quattrocento Sans', --display 'DM Serif Display'.
 *
 * All selectors are scoped under .ra-booking to avoid conflicting with
 * WordPress or any parent page styles.
