- new crate lightcraft-preview (L3): 128-bit content hashing (SipHash-1-3), cost-bounded Lru, DiskCache (JPEG q90 files keyed by content hash + settings hash + size + RENDER_CACHE_VERSION; temp+rename writes; LRU prune by mtime to 80% of budget; corrupt files dropped), PreviewCache (memory LRU over disk), JobPool (per-slot dedupe, priorities, reprioritize/drop, inline mode for wasm). - engine: Session::thumb_job buckets thumbnails to 128/256/384/512 and serves them from the cache without decoding the source; decoded thumbnail sources now in a 384 MB LRU (was unbounded); library attaches <library>/thumbs; library.info cache stats; library.clearPreviews. - ui-egui: Renderer runs on JobPool; thumbnails scrolled out of the prefetch area are dropped from the queue; on-screen thumbnails get re-prioritized; ui.inspect reports in-flight renders + thumb textures. - Demo library (24 photos): grid fully drawn 4.4 s cold -> 0.21 s warm (24/24 disk hits, no source decoded).
