   Section: Project Detail Modal + Photo Carousel
   ----------------------------------------------------------------
   Fullscreen overlay launched from .work-card clicks (homepage
   "Recent Work" and the Projects page grid). Renders project info
   alongside a swipeable photo carousel without leaving the page.

   On WP migration: the same DOM is mounted by project-modal.js in
   the theme. Cards keep their permalinks for SEO/no-JS fallback;
   the JS calls preventDefault() and opens the modal instead.
