/* BagBack design system — Material Design 3 (M3), light scheme, sized up for readability.
   One file for every page: the claim builder, the airport checklist, airline and guide pages, case and signing pages,
   the reviewer queue, and error pages. Tokens follow the M3 naming (md-sys-*); components follow the M3 specs with
   touch targets held at 48px or more and body text at 18px, because the audience skews older.
   Type: Roboto (M3 default) / Roboto Mono for references and figures. */
