/* CRM Kepler — Design system "marine/ink" (D-ui-design-system, Fase A1).
   SHELL ONLY: tipografia base + cornice (sidebar/topbar/layout). La libreria
   componenti (card, badge, btn, tabelle, chip…) e lo stile dei form sono la
   Fase A2 — NON in questo file. Il design system sta SOPRA Bootstrap: questo CSS
   è caricato DOPO bootstrap_css per vincere in cascata, ma usa i token di
   tokens.css (caricato prima). Niente reset globale: il contenuto interno delle
   pagine resta governato da Bootstrap finché A2 non lo riveste. */
