/* WG branding for the scheduler, in light and dark themes.
 *
 * Adapted from wg_branding.css (a Bootstrap 5.3 theme). This app is built with Tailwind, so instead of
 * loading Bootstrap (whose .badge/.border/.rounded/.table classes clash with Tailwind's) we take its
 * design tokens and components:
 *   - Tailwind's palette, font, radius and shadow are mapped to the brand in base.html
 *     (tailwind.config), through the --c-* theme tokens below so they switch with the theme
 *   - this file adds the brand's components: navbar, buttons, form fields, focus ring, chips
 * The theme is chosen by data-theme on <html> (set before first paint in base.html): the viewer's
 * saved choice, else the device's light/dark setting.
