/* gbr-reviews — Google Business Reviews component (aether.dev)
 * Pure progressive enhancement: style the server-rendered (baked) markup;
 * gbr-reviews.js only refreshes numbers/dates/cards from the sync endpoint.
 *
 * Layouts (modifier on the .gbr root):
 *   .gbr--marquee — two horizontally infinite-scrolling rows in a rounded
 *                   container (default for new sites)
 *   .gbr--grid    — the previous static 3/2/1-column grid
 * Bare .gbr behaves as .gbr--grid (back-compat with earlier embeds).
 *
 * Theme via CSS custom properties (see README.md theming table). */
