/* F35.W1 — ResourceGroupChipsBar shared premium CSS.
 *
 * Canon Linear filter chips / Notion databases group filter / Cal.com Event Types.
 * Surfaces (Calendar v2, Booking Wizard, Public Wizard, Resources tab) подключают
 * этот файл через <link rel="stylesheet">.
 *
 * Совместимость: resource-editor.css содержит исторические дубли (F26.W1) — оставлены
 * как fallback. Specificity идентична. Cleanup дублей — отдельная задача F35.W7.
 *
 * Premium features (поверх F26.W1 base):
 *   - Focus visible (keyboard navigation accessibility)
 *   - Mobile horizontal scroll snap (touch target ≥44px)
 *   - Keyboard hint badge (number key indicator при Alt-hold)
 *   - Reset button + Manage button consistent styling
 *   - Empty state helper (когда filter даёт 0 результатов)
 *   - Dark theme support через prefers-color-scheme
