Hugo pre-computes a JSON array of {img, video} entries per gallery item
(WebP 1200w src + optional mp4 src). Alpine reads the array and manages
lightbox state (open/idx/prev/next/close).
Features:
- Click any card → opens fullscreen dark overlay (bg-void/95 + backdrop-blur)
- Videos: controls, autoplay, x-effect reloads src on navigate
- Images: full-res WebP centred with object-contain
- Keyboard: Escape closes, ←/→ navigate
- Dot indicators: active dot expands (heat colour)
- Prev/next arrow buttons (hidden when only 1 item)
- Grid cards: cursor-zoom-in, pointer-events-none on media so click
always hits the <figure>
- Teleported to <body> via x-teleport to avoid stacking context issues
- Gradient-line accent top and bottom of overlay

Add layouts/partials/img.html helper that resizes and converts any Hugo
page-resource image to WebP, emitting a responsive srcset at multiple
widths. Wire it up to every image rendering site:
- post-card.html: thumbnail (600w/1000w) + avatar (64px WebP)
- post-card-large.html: featured card background (800w/1200w)
- posts/single.html: banner (1200w/1800w, eager) + gallery (800w/1200w)
- author-card.html: avatar (96px WebP, 2× retina)
Result: banner.png 7.9 MB → 496 KB WebP at 1800w (−94 %).
Hugo caches processed images in resources/_gen/ across builds.
