   L3K SERVICE — style.css
   Pronto intervento a Torino · https://www.l3kservice.it/
   --------------------------------------------------------------------------
   CSS modulare e mobile-first. Nessun framework (no Bootstrap/Tailwind).
   Un unico foglio di stile per tutte le pagine del sito.
   Breakpoint di riferimento: 600px, 768px, 1024px.
   Metodologia: mobile-first (regole base = mobile, poi min-width) + BEM.
   Layout: Flexbox per le righe di componenti, CSS Grid per le griglie.
   NB: dopo ogni modifica incrementare la versione in
   <link href="style.css?v=..."> per superare la cache di 1 anno (.htaccess).
