   Patente Guida — foglio di stile delle PAGINE PUBBLICHE SEO
   (auto/segnali/, auto/quiz-argomento/ — generate da
    scripts/generate-seo.mjs, vedi docs/fase3-plan.md passo 1b)

   Autonomo di proposito: NON importa css/style.css, che porta con
   sé tutta l'interfaccia dell'app (nav, schermate, overlay) e
   costerebbe ~100 KB a un visitatore che arriva da Google per
   leggere un segnale. Qui servono solo tipografia, colori e quattro
   componenti. Stessa identità: nero profondo, hairline, maiuscolo
   spaziato, rosso corsa.
