/* ============================================================================
   Banner cookie + pannello "Preferenze cookie" (D0071 §1.3)
   ----------------------------------------------------------------------------
   File SEPARATO da main.css di proposito: il CSS servito dal sito e' un build
   con hash (dist/static/main-D-hUiRpk.css) che non va toccato a mano, e non
   esiste uno script di build. Questo file vive in due copie identiche:
     frontend/styles/cookie-consent.css   (sorgente)
     dist/static/cookie-consent.css       (servito)
   Si modificano insieme.

   Usa le variabili del tema definite in main.css (--bg-2, --border, --text,
   --muted, --red, --font-display): cosi' il tema chiaro (html[data-theme=light])
   viene gratis, salvo le poche ombre/tracce ritoccate in fondo.

   Il BANNER non e' un cookie wall: niente overlay, il sito sotto resta usabile.
   Solo il PANNELLO preferenze e' modale (backdrop + focus trap nel JS).
