/* What Bootstrap does not have.
 *
 * Deliberately short. Bootstrap plus the tokens in theme.css covers cards,
 * tables, forms, modals, badges, spacing and the grid; templates use its classes
 * directly. This file holds the application shell, which no CSS framework
 * provides, and the few patterns shared by more than one screen.
 *
 * Colours come from theme.css's tokens (--surface, --border, --text-*,
 * --tone-*), never from a hex code: a colour written here for one theme is the
 * colour that breaks in the other.
 */
