/* Footer comune delle pagine progetto (lo scrive scripts/footer-sito.cjs).
   Stessi colori, carattere e pulsanti del menu dei lavori e di About me: ogni progetto ha il suo
   stile, il footer è la cornice del portfolio ed è uguale dappertutto.
   Tutte le regole partono da .site-footer, così gli stili delle singole pagine non lo toccano. */
