- Add MediaViewer overlay for full-size image/video display with prev/next
navigation, direction keys, counter, and adjacent preloading
- Recipe modal: click preview image/video opens full-size viewer
- Model showcase: click any example image/video opens viewer with full
gallery navigation; blurred NSFW content opens directly to clear view
- Use Map<Element, number> for DOM-index mapping instead of URL comparison
to avoid index mismatch from lazy-loaded vs data-attribute URLs
