/* ============================================================================
   TheReceiptHound — Auth surfaces + 404
   login / register / forgot-password / reset-password / verify-email / 404

   Split shell (auth-side.png on login, register-side.png on register),
   1:1 card-top art on the single-card pages (forgot-scent / reset-key /
   verify-mail), captcha row, and the "lost trail" 404 page.

   Relies on the shared design system:
     • form fields are styled by the .form-group descendant rules in
       components.css — no .input classes needed in auth markup;
     • focus rings use the --focus-ring-soft token (variables.css), repainted
       per-tenant by theme.js;
     • .auth-container / .auth-card / .auth-description base styles live in
       layout.css — this file only adds the split shell and auth-only pieces.
