1//! Progress reporting for long-running Model Hub downloads (LLM fetches).
2
3/// One progress update emitted during a long-running download.
4///
5/// `stage` is a short label (e.g. `"download"`, `"verify"`, `"done"`).
6/// `current` / `total` are stage-local byte/step counts; `total == 0` marks a
7/// non-quantifiable stage. The Tauri command layer maps these to progress
8/// events the frontend renders as a bar.
