/*
 * Circular Commuting — design system condiviso (home, beta, versione semplificata).
 * Pastelli opachi su un verde foresta profondo, Manrope con titoli leggeri, bordi sottili, ombre quasi impercettibili.
 * Segni propri: il mare pastello in movimento, le formine trasparenti (crocette, cerchi, rombi, triangoli),
 * le icone a tratto 1.5. Documentazione: _dev/DESIGN-SYSTEM.md
