/* ═══════════════════════════════════════════════════════════════════════════
   📱 APP SHELL — profilo "app" (TWA / PWA installata / ?shell=app)

   Cosa fa: sostituisce intestazione e footer del sito con
     • barra in alto  (logo/indietro, titolo sezione, preferiti, info)
     • navigazione    (Podcast · News · Cerca · Quiz · Statistiche)
       - layout COMPATTO (< 600px, telefono in verticale): barra in basso
       - layout LARGO    (≥ 600px, tablet / telefono in orizzontale): barra laterale
       - layout LARGO ma BASSO (altezza ≤ 500px, telefono in orizzontale): barra più sottile
       - layout ESTESO   (≥ 840px e altezza > 500px): menu laterale con testo

   Il sito web NON cambia: tutte le regole sono sotto html[data-shell="app"]
   (l'attributo è impostato dallo script all'inizio di App.razor).

   Solo variabili del tema (--bg-*, --text-*, --accent-*, --border-color):
   tema chiaro/scuro funzionano senza regole aggiuntive. Nessun colore fisso.
