/**
 * Travel Offers Plugin — Front-end styles
 *
 * Architecture: BEM (Block__Element--Modifier)
 * Blocks: top-offer-block, top-offer-grid, top-hotel-box, top-destination-box,
 *         top-price, top-stars, top-rating, top-badge, top-skeleton, top-empty-state
 *
 * Breakpoints (matching ACF device_visibility field):
 *   Mobile:  < 768 px
 *   Tablet:  768 – 1279 px
 *   Desktop: ≥ 1280 px
 *
 * Custom properties are set by RenderContext::gridColumnVars() inline
 * on .top-offer-grid so grid columns are driven entirely by PHP/ACF config.
