/*
 * Book Buddy — public site design system.
 *
 * One stylesheet for every customer-facing page: courses, course detail,
 * checkout, pay, event application, ticket, product. Before this, each of
 * those pages carried its own <style> block with its own purple palette, so
 * the CMS pages looked nothing like bookbuddyacademy.com, which the WordPress
 * cards plugin already dresses in the brand.
 *
 * The tokens below are lifted verbatim from
 * wp-plugin/bookbuddy-connect/assets/bookbuddy.css so a card rendered by the
 * shortcode on the marketing site and a card rendered here are the same
 * object. Change a brand value there and change it here; nowhere else.
 *
 * Namespaced .bb- throughout. Bare element selectors are used only for page
 * furniture (body, headings, form controls) because these are our own whole
 * pages, not a widget dropped into someone else's theme.
 *
 * There is deliberately NO dark-scheme block, matching the plugin: these pages
 * are a fixed part of a light brand, and repainting them for the visitor's OS
 * setting made them stop matching the rest of the site.
