/* ════════════════════════════════════════════════════════════
   LIGHTBOX  (pure CSS, no JavaScript — uses the :target trick)
   ════════════════════════════════════════════════════════════
   HOW IT WORKS:
   Each thumbnail is a link to #lightbox-N. Each lightbox-N is a
   full-screen overlay, hidden by default, shown only when its
   id matches the URL hash (:target). A close link resets the
   hash back to #_close (an empty target), and clicking the dark
   backdrop does the same.
