   DIGYPAY — FOGLIO DI STILE DEL NUOVO SITO
   =====================================================================
   Come leggere questo file: è diviso in sezioni numerate. Ogni sezione
   spiega cosa fa e perché. Nessun framework: CSS semplice, così il sito
   resta leggero (importante per Google e per chi naviga da telefono).
   ===================================================================== */

/* ---------------------------------------------------------------------
   1. VARIABILI DI COLORE E TIPOGRAFIA
   Tutti i colori stanno qui, in "variabili". Se un giorno cambi il blu
   del marchio, lo cambi in UN solo punto e si aggiorna tutto il sito.
   I colori vengono dal logo DigyPay (blu #2E58A6, arancio #FF6204).

   2. BASE
   Azzeriamo i margini del browser e impostiamo il testo di base.
   "box-sizing: border-box" fa sì che padding e bordi stiano DENTRO la
   larghezza dichiarata: i calcoli del layout diventano prevedibili.
