/* Contracting Back Office — components and tokens, taken as-is from the UX prototype
   (docs/design/contracting-backoffice-prototype/backoffice.css, UX-CONTRACTS-BO-001 §7). Product additions: app.css.
   Tokens: same names as tripcloud-theme.css (v1) and cp-v2.css (v2), with fallbacks so the file
   opens on its own. Back Office is denser than the CP: smaller radii, 14px base, 40px controls.
   Logical properties only (inline-start/end), so dir="rtl" on <html> mirrors the whole layout. */
