/* ============================================================
   LIGHTBOX — full-size viewing for work that is not a website
   ------------------------------------------------------------
   Some projects have no live URL to link to: the deliverable is
   the artwork. A card for those opens the pieces at a size where
   they can actually be read, rather than linking nowhere.

   Built to the same rules as the fullscreen menu in layout.css —
   it takes the whole viewport, locks the page behind it, traps
   focus and closes on Escape — so there is one overlay
   behaviour on the site rather than two.
