/* ============================================================================
 * components.css
 * Gestionale CONI Emilia Romagna — Fase 3, Task 3.2
 * Master Plan v3.4, Sezione 6.1
 *
 * Componenti UI riutilizzabili. Ogni componente usa SOLO variabili
 * da design-tokens.css — nessun valore hardcodato.
 *
 * STRUTTURA:
 *   1. Bottoni (.btn, .btn-primary, .btn-secondary, .btn-danger, .btn-ghost)
 *   2. Input e form (.input, .select, .form-group, .form-error)
 *   3. Toast notifications (.toast-container, .toast)
 *   4. Modal di conferma (.modal-overlay, .modal)
 *   5. Skeleton loading (.skeleton, .skeleton-text, .skeleton-circle)
 *   6. Badge stato (.badge)
 *   7. Avatar generato (.avatar)
 *   8. Tag territorio (.tag)
 *
 * DIPENDENZE:
 *   - design-tokens.css (deve essere caricato PRIMA)
 *
 * CONVENZIONI:
 *   - Classi BEM-like senza nesting profondo: .componente, .componente-variante
 *   - Nessun colore hardcodato: solo var(--token)
 *   - Transizioni tramite var(--transition-fast) o var(--transition-base)
 *   - Responsive dove applicabile (breakpoint documentati in design-tokens.css)
 * ============================================================================ */
