In-post event gallery block + lightbox; mobile polish
- Reusable "Photos from the event" grid (shows 5 thumbnails + "+N more") that opens a full-screen lightbox (arrows / keyboard / swipe / Esc); added to the Meet Student Slovenia 2024 post as the pattern - New css/components/_lightbox.css + setupLightbox() in main.js (injects one shared overlay, wires any .js-lightbox grid) - Mobile polish: gallery albums go single-column on phones, two on tablets; event-gallery grid 3-up on mobile; lightbox sizing/controls tuned for small screens Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
