/* ============================================================================
   legacy.css — stili per i moduli legacy (notifications.js, field-creator.js,
   pdf-editor.js) adattati alla shell nuova.

   Contiene:
   1) Sistema modale/notifiche (.modal-overlay/.modal/...) usato da notifications.js
      e dal modal "Configura Campo" di field-creator.js.
   2) Modale di progresso (.modal-progress/.progress-step/...).
   3) Pannelli dell'editor avanzato (#pdf-editor-toolbar, #pdf-properties-panel,
      #pdf-editor-controls, .pdf-editor-overlay, .toolbar-component, ...).

   I bottoni footer legacy usano classi .btn/.btn-primary: qui sono SCOPATI dentro
   .modal-footer per non collidere con la .btn della toolbar in /app/css/app.css.

   THEME-AWARE VIA TOKEN: tutte le superfici/bordi/testi usano i token del design
   system (--panel, --panel-2, --border, --text, --text-dim, --accent, --radius).
   Così luce/scuro seguono automaticamente il tema della shell → NON serve più il
   blocco :root[data-theme="dark"] con esadecimali duplicati (rimosso).
   Restano hardcoded solo: le pastiglie di stato colorate (badge success/error/
   warning/info) e i gradienti dell'editor avanzato, volutamente identitari.
