/* preserved-l2.css
   Site-specific styling for the /preserved-locomotives L2 page.

   Wraps each H2 prose section in a brass-gold-bordered card that
   matches the homepage card aesthetic, alternating between two
   subtle surfaces (clean card / faintly tinted) so the four sections
   don't read as one block of white. Adds a thumbnail mini-card grid
   for the [preserved_loco_thumbs] shortcode.

   Uses the existing site-theme variables (--primary-color,
   --secondary-color, --card-bg, --background-alt, --border-color)
   so light (warm off-white + crimson + brass) and dark (navy + brass
   + crimson) themes are handled by the palette already in place.
   Brass gold border (#C9A84C) is used the same way as every other
   card / panel on the site. */
