Replace the placeholder browser script with the PLAN.md upload flow. The static UI now creates upload records, slices the selected file into fixed-size chunks, uploads missing chunks with a concurrency pool of three workers, retries failed chunks with exponential backoff, pauses via AbortController, and completes the upload once the server has accepted every chunk. Persist pending upload records in IndexedDB and render them in the page so a reload can resume from server-authoritative progress. When the File System Access API is available, the app stores a file handle and asks for read permission during resume; when it is unavailable or permission is denied, the same pending record resumes after the user reselects the matching file. Browser state is helpful but not trusted: every resume starts by querying the server for completed chunks. Add a JavaScript syntax check to the justfile, update the static-page test and documentation, and extend TESTS.md with the manual resume scenarios that still need real-browser repetition.

upl
upl is a small personal resumable upload service. The intended deployment is:
browser -> nginx -> upl Rust server -> local filesystem
The first implementation milestone provides the Rust server shell and static
browser UI. Upload metadata, chunk persistence, resume state, and completion
assembly are tracked in PLAN.md and will be added in later coherent slices.

Configuration
UPL_BINDsets the listen address. It defaults to127.0.0.1:3000.UPL_STATIC_DIRsets the static asset directory. It defaults tostatic/inside this repository.UPL_DATA_DIRsets the upload data directory. It defaults todata/inside this repository.- The server accepts request bodies up to 64 MiB, which leaves room for the
planned 16 MiB upload chunks and matches the nginx example in
PLAN.md.
Common Commands
Use the justfile for routine tasks:
just check
just run
just check also syntax-checks the static browser JavaScript with node.
