The 5×10 metadata batching only staggered the cheap layer (JSON); thumbnails load as independent <img> requests and clustered, so tiles "popped in together" after a wait. Two changes: - GalleryItem reveals each tile when ITS OWN thumbnail fires @load (with an onMounted complete-check for cached thumbs), playing a showcase-style flip-up entrance. Tiles now cascade in natural load order instead of all at once. Honors prefers-reduced-motion. - gallery store does ONE initial fetch (limit=50) instead of 10 serial /scroll round-trips. Fewer RTTs, faster first paint; the reveal-on-load is what makes appearance progressive now. Infinite scroll pulls 25/trigger. Tests: GalleryItem gains is-loaded only after @load; loadInitial issues exactly one scroll request at the initial limit. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
