/* ==========================================================================
   SoftEdu — Candidate access screen.

   A dedicated stylesheet for this one page, deliberately NOT auth.css.
   auth.css/app.css's token names (--paper, --card-white, --font-display,
   etc.) are load-bearing for the rest of the app — staff login, the
   dashboard shell, the admin console — so this file never touches them;
   it defines its own tokens and its own markup contract, entirely
   sandboxed to candidate-login.blade.php.

   Design idea: an examination admission card, not a SaaS login card.
   A hard-edged two-panel masthead (ink panel + paper panel) rather than a
   rounded card floating on a grey field — the split IS the layout, not a
   card centered on a background. Fraunces/Work Sans/IBM Plex Mono are
   already this product's type system (see app.css) — the candidate portal
   is the one place that system never actually reached; this is that
   catch-up, not a new identity.

   One committed visual world, not a light/dark pair — an admission card
   reads the same regardless of the device it's shown on, the same way a
   printed one would. Every color below is set explicitly rather than
   inherited, so that holds on any screen.
