 * AreaTeam v3 — Component styles
 * ============================================================
 * Stili dei 13 componenti del design system.
 * Importare DOPO tokens.css e base.css.
 *
 * Ogni componente:
 *  - usa SOLO var(--at-*), mai colori hardcoded
 *  - dichiara override theme-specific in fondo alla sezione
 *  - distingue .at-label (chrome UI, uppercase in V3) da .at-data (DB content)
 *
 * Sezioni in questo file:

 *   §4 at-pill          (atom)
