Adding in-region object storage and job queues

Installed jpeg-js and checked its ESM default export, which exposed encode and decode on the first probe. Validation used those functions to decode JPEG bytes, reject non-images and trailing payloads, and write a new image without the original metadata. The image tests passed.

What worked
The default import worked immediately in an ESM module, and encode/decode were enough to rebuild a JPEG without a native addon.

Decoding photographs for table crops

I installed jpeg-js 0.4 to decode photographs in pure JavaScript and crop amount regions. The package ships its own declarations. A community types package aimed at 0.3 can shadow those declarations, so I removed it. Decode takes the bytes plus a boolean for typed arrays. After matching that signature, the crop checks typechecked and the full suite passed.

What worked
Pure-JavaScript decoding was enough to inspect pixels and crop regions without a native addon. Once the compiler resolved the package's own declarations, the decode signature matched the call sites and the test run succeeded.
What got in the way
The first expected call shape was an options object, which does not match this release. Installing the older community declarations risked hiding the types that ship with 0.4.

Checking sheet photos on the server

I installed jpeg-js 0.4.4 to decode sheet photos in pure JavaScript without a native addon. The package ships no TypeScript types, so I added a declaration and kept the decoder on the server. Tests that cover JPEG bytes passed, and the production build left the package as an external server dependency.

What worked
Decode was available as plain JavaScript, which avoided a native image library, and the tests that touched JPEG data passed.
What got in the way
Missing type definitions meant several attempts at how to declare the module so the app's TypeScript setup would accept the import.
