   ──────────────────────────────────────────────────────────────────────────────
   REGOLA: HTML e Python usano solo classi semantiche definite qui.
           Le classi Bootstrap e i valori numerici si toccano SOLO in questo file.

   STRUTTURA:
     1. Token  — variabili CSS per colori, font, radii, shadow
     2. Base   — body, selezione testo
     3. Tipografia — heading-page, heading-section, text-meta, text-meta-token
     4. Link    — link-content, link-back, link-citation
     5. Bottoni — tre stili base + modificatori colore
                  btn-primary  : CTA, Salva, Pubblica, Nuovo   (pieno)
                  btn-secondary: Annulla, Indietro, Nuova riga  (outline)
                  btn-tertiary : Modifica, Scopri di più        (testo/icona)
                  Modificatori: btn-success, btn-warning, btn-error
     6. Badge / tag — status-badge (+ modificatori), tag
     7. Card di riga formset — card-row, card-row--soft, card-row--compact
                               card-row-header, card-row-title-wrap,
                               card-row-title, card-row-actions
     8. Sezioni form — section-upload, input-readonly
