apps/lightcraft-web runs the egui UI in the browser (eframe web, glow/WebGL2):
procedural demo library on load; in-memory imports via file picker
(Cmd+Shift+I) and drag-and-drop (MemStore + bytes-based engine hooks);
export goes through app.export and downloads in the browser; `?bench` logs
first-frame and slider latency. `cargo xtask web [--serve [port]] [--dev]`
builds with the matching wasm-bindgen CLI into <target>/web/; the web app is
part of the CI wasm check. Wasm fixes: lazy profiling Instant in pipeline,
web-time clocks in ui-egui (render timings were 0 on wasm). Docs: docs/web.md.
No persistence on web yet.

- 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).
