 **Versioning:** [Nerdbank.GitVersioning](https://github.com/dotnet/Nerdbank.GitVersioning) — configured in `version.json` at the repo root. Major+minor is hand-bumped; patch comes from git-height. `main` is the public-release ref (stable versions); everything else gets prerelease tags. GitVersion is still installed as a transitional helper for `MajorMinorPatchVersion` in `Build.cs`; full removal is a follow-up.
