/* ==========================================================================
   Projects — listing (/projects) and detail (/projects/<slug>)

   Reproduces the original .case-* / .tags-list design with a structured,
   readable ruleset. Everything is namespaced `pjt-` so it never collides
   with the legacy classes still used by studies.php / detail-products.php.

   Palette is driven by the site tokens declared on :root in style.css
   (--secondary-blue, --brand-color, --main-yellow, --main-text).
