/* Portal-specific styles. Loaded alongside the main site's css/main.css,
   which supplies design tokens, .btn, .form-group, .eyebrow and body/base
   resets. Organised as a "trail" rather than a stack of dashboard widgets —
   numbered waypoints down a side rail, ledger-style lists instead of
   floating cards, flat ink-bordered panels instead of drop shadows. */
