   FOX MADRID — La Carta · VARIANTE 1 — "Páginas satinadas"
   ==========================================================================
   Direzione: accordion chapter-style
   Pattern: ogni piatto = una "scheda" ripiegata. La riga standard
   (nome · leader · prezzo) è sempre visibile. Cliccando sul "+" si apre
   un pannello "giro pagina" che rivela: descrizione integrale + lista
   allergeni (Contiene / Puede contener trazas).
   Vincoli: zero icone sui piatti. Zero filtri. Zero tooltip hover-tipici.
   L'informazione allergenica è solo on-demand, ma la modalità è
   click-and-expand (no hover): privilegia accessibilità tastiera e
   mobile, ed evita il rumore visivo dei popover continui.
   Diversità strutturale dalle altre varianti:
   - dossier-carta (baseline): icone sotto, legenda in fondo pagina
   - dossier-carta-v2 (La Mesa): filtro allergeni per tavolo
   - codex-1/2, deepsk-1/2: micro-badge o rimandi numerici
   - buffy-1 (filtro): filtro interattivo sticky
   - buffy-2 (editoriale): popover hover per piatto
   - antigravity-2 (spread): riproduzione fisica con spread+cornice
   Qui: nessuno schema di marcatura. L'utente dichiara interesse
   cliccando; il pannello si apre con animazione.
