/* Parts Ledger stylesheet.
   A quiet, minimal system: one neutral scale, hairline borders instead of shadows, a single accent
   reserved for links and focus, and status colours that meet WCAG AA on their backgrounds.
   Order: tokens, base elements, app shell, shared components, page layouts, responsive rules. */
