/* =============================================================================
 * Pllato Suite — UI Components
 * =============================================================================
 *
 * Семантические primitive-компоненты на новых токенах (design-tokens.css).
 * Применяются в новых/редизайн-секциях. Existing legacy-классы (.card-old,
 * .deals-toolbar, и т.п.) пока не трогаем — мигрируем модуль за модулем.
 *
 * Принципы:
 *   - Все размеры через токены (height, padding, radius, font).
 *   - Один паттерн = везде (Card/Badge/Tabs/Field/Modal).
 *   - States: hover, focus-visible, active, disabled, empty.
 *   - Keyboard: tab order + focus indicator (жёлтое glow) везде.
 *   - Long values: ellipsis + tooltip pattern.
