Brandon ThomasandClaude Opus 5.5 ebc73bb7b4 Issue #107: Web build: data-safety fixes for libraries kept in the browser
- File > Back Up Library... (web): a zip of the catalog files and every
  stored original, built entry by entry; Restore Library from Backup...
  reads it into a new library folder and switches only when complete
  (the previous library stays in storage).
- Failed flushes to browser storage make the catalog Store refuse
  writes, so changes show as unsaved (top-bar warning) and are retried
  every 2 s instead of being lost silently.
- A picked/dropped photo whose bytes can't be stored is not added.
- One tab per library (Web Locks); a second tab shows a message.
- Notices: storage not persistent, library failed to open (temporary
  session), experimental build; ?reset asks first; a panic shows a
  message instead of a frozen page; long toasts wrap.
- Hosting: _headers/.htaccess no longer mark the unhashed .js/.wasm
  immutable; HOSTING.md rewritten for the actual build.

//! LightCraft in the browser: the same egui UI as the desktop app, compiled to WASM.
//!
//! Build with `cargo xtask web` (→ `target/web/`), then serve that folder over HTTP (see
//! `docs/web.md`). Differences from the desktop host:
//! - the library lives in browser storage (OPFS, or IndexedDB where OPFS can't be written from the
//! main thread): catalog journal, presets, view state and prefs are mirrored in memory and
//! flushed in the background ([`files`]); imported originals are stored by content hash
//! ([`store`]); a new library starts with the procedural demo photos;
//! - renders run in Web Workers, each a second instance of this module ([`wire`], `workers`), and
//! fall back to the main thread (one job per frame) if workers can't start;
//! - export downloads the file through the browser.
//!
//! `?bench` in the URL runs a scripted first-paint / slider-latency measurement and logs it to the
//! console (see [`bench`]); `?store=idb` forces the IndexedDB backend, `?store=memory` disables
//! persistence and `?workers=0` renders on the main thread.
