/* Global infographic lightbox (companion to lightbox.js).
   Any `.gx-zoomable` element advertises zoomability (cursor + focus ring +
   hover lift) and opens full-screen in a native <dialog class="gx-lightbox">.
   Works in both themes via the base tokens; reduced motion disables the
   zoom-in animation. CSP-safe: pure stylesheet, no imports, no URLs. */
