 * auth.css — login.php + register.php only (loaded via the page `css` opt).
 *
 * A calm, premium two-column authentication experience: the form on the left,
 * a quiet market panel on the right. Everything is token-driven; no gradients
 * louder than the rest of the product, no glow, no flashing. The market panel
 * is decorative + informational — it never blocks the form and collapses to a
 * contained, horizontally-scrolling strip on small screens.
