/* =========================================================================
   v4 — «Cabina di comando»
   La home e' un cruscotto: consolle scura a quadretti (la carta millimetrata
   di chi legge i numeri), tessere-strumento con grafici che si disegnano,
   pannelli con l'angolo tagliato a 45 gradi del simbolo DF.
   Colori: solo quelli del marchio (navy e scale gia' in style.css, arancio come
   colore del segnale). Arancio mai come testo su fondo chiaro: --accent-ink.
   Caricato dopo style.css: qui si sovrascrive, non si ricomincia.
