+reads the version from `Cargo.toml` (the single source of truth) and
+accepts an optional suffix for pre-release builds:
 
 ```bash
-./build-release.sh              # uses git describe for version
+./build-release.sh              # uses version from Cargo.toml (e.g. 1.0.0)

 ```
 
 This produces a `release-artifacts/` directory with:
