Session recovery: more than one pending snapshot adds a 'Restore all' button to the Recover Drawing modal — every snapshot goes through the exact same guarded path as a single restore (deleted only after its own open succeeds). The open-tab list and active tab persist to localStorage on web (open/save/close) and the remembered tab is re-selected once a restore batch settles; the modal notes how many drawings the session had. Nothing is auto-opened. Deep links: ?file=<url|name> opens a drawing at boot. http(s) URLs must end in .dwg/.dxf and are fetched with the same streaming, 64 MB-capped, 8 s-deadline reader the remote images use, then go through the guarded open queue; cross-origin opens announce the origin first. Bare names resolve from the browser's recent storage, with a hint when absent. Everything else (file:, javascript:, drive letters, non-drawing tails) is refused with a console note. Offline PWA: the app was installable (manifest) but downloaded its 55 MB bundle on every visit. A cache-first service worker now serves the whole bundle from Cache Storage after one online visit — navigations network-first so updates land, hashed assets stale-while-revalidate, non-GET/cross-origin passthrough, old caches cleaned on activate, and the waiting-worker update flow documented. The build wrapper stamps the cache version from the bundle hash and hard-fails if sw.js is missing or unstamped. Also fixes a locale group mismatch on the DATALINK pick notice (catalog said a display group that does not exist in the ftl sources).
