/* THE SIGN-IN PAGES (2026-10-22): login now; signup, verify-email, forgot-password and
   set-password move onto the same shell next (includes/auth_shell.php). One file, both
   themes: the page sets data-theme on <html> from the portal's dpzTheme choice before it
   paints. Colours are the site's own tokens (the logo's #0066FF to #00FFFF, the portal's
   light and dark palettes); navy and violet appear only in the brand panel.
   Small text uses --muted, which passes WCAG AA in both themes (--dim does not).
   Review (2026-10-23): placeholders (--ph) at 4.5:1 or more, field borders (--field-line)
   at 3:1 or more (WCAG 1.4.11), the green notice at 4.9:1 in light; the form and the panel
   fit 1366x768 and 1280x720 without a scroll; tablets centre the form. */
