/* ==========================================================================
   Axura — Foglio di stile condiviso delle pagine di APPROFONDIMENTO
   Servito da /it/assets/approfondimenti.css

   PERCHÉ ESTERNO E NON INLINE
   La CSP in .htaccess autorizza gli stili inline solo tramite hash SHA-256,
   che cambia a ogni singolo carattere modificato. Servendo questo file da
   'self' (già consentito da style-src) le pagine di approfondimento si
   modificano liberamente senza mai ricalcolare un hash.

   PERCORSI ASSOLUTI
   I @font-face usano /it/fonts/… e non fonts/… : le pagine di
   approfondimento vivono in sottocartella (/it/brand-journalism/) e i
   percorsi relativi della home si romperebbero.

   I token, la navbar, il footer, la skip-link, l'accordion FAQ, la CTA e il
   pulsante "torna su" sono allineati 1:1 a /it/index.html per garantire
   parità visiva e di accessibilità. Le classi con prefisso .appro- sono
   invece specifiche degli approfondimenti.
