Document the minimal design for a personal large-file upload app that can
resume after browser, network, or server interruptions. The plan keeps the
first version intentionally small: one Rust server, one static browser UI,
filesystem-backed upload metadata, raw chunk uploads, and no database or
third-party resumable upload protocol.
The deployment notes include nginx as the external TLS and access-control
layer, with the Rust server bound behind it and upload-specific proxy settings
called out.
Test Plan:
- git diff --cached --check
