   PORTFOLIO ATLAS — panels.css
   The slide-in placard and ALL of its injected content.

   panels.js injects markup into #panel-body using the classes
   below (.card / .page and children). Project cards aim for
   museum-placard quality: serif headers, monospace data labels.

   Consumes tokens from style.css :root. Desktop: right-edge
   drawer; mobile (< 768px): bottom sheet. Motion respects
   prefers-reduced-motion.
