/* ------------------------------------------------------------------
 * Reusable UI components, shadcn-flavoured.
 *
 * Visual rules live on `[data-slot="..."]` (and `data-variant` /
 * `data-size`) selectors that mirror the shadcn registry vocabulary
 * (Button, Card, Badge, Dialog, Toast, Progress, Toggle Group,
 * Navigation Menu, Table, Accordion, Alert, List, Item, ...).
 *
 * Legacy class names (.btn, .modal-backdrop, .modal-close, .toast,
 * .nav, .lang-switch__btn, .preview-card, ...) stay on the elements
 * because JS in `assets/js/main-shared.js`, `assets/js/main-landing.js`,
 * `assets/js/checklist.js`, and the
 * analytics module query the DOM by them. They are kept as compound
 * selector list members where rules apply, or as state hooks for
 * .open / .is-visible / .is-active / .is-anchor-scrolling toggles.
 *
 * Brand tokens come from `assets/css/tokens.css` — colors and shadow
 * recipes are unchanged from the pre-shadcn design system.
