/* ==========================================================================
   VRDevAI — project detail modal

   Opens from a case-study card. Built on native <dialog>: the browser gives
   focus trapping, Escape, inert background and the top layer for free, and
   every one of those is a bug waiting to happen in a hand-rolled modal.

   Progressive enhancement, same rule as the rest of the site: with JS off the
   cards stay exactly as they are and still link to case-studies.html. Nothing
   here is required to read the page.
