/* ============================================================================
   lane — foglio di stile della vetrina pubblica
   Scritto su misura sul brand book (identity/brand_identity.md, v1.0).
   Nessuna dipendenza: niente Bootstrap, niente AOS, niente icone esterne.

   Principi:
   - dark-native: antracite di base, il cyan resta un accento (<=10%)
   - niente riquadri attorno ai contenuti: le sezioni si separano con
     filetti, tipografia e spazio
   - i pochi contenitori ammessi sono superfici funzionali (bottoni,
     campi, cornici dei telefoni), mai involucri di sezione
   ========================================================================== */
