"""Build a minimal NuGet v3 static feed around one real, `dotnet pack`-built
.nupkg, for integration-testing the `nuget` module of id-configurator.
Only two resources are populated: the flat container (`PackageBaseAddress`,
used to enumerate versions and download the .nupkg directly) and the
top-level service index pointing at it. `dotnet add package`/`dotnet
restore` with an explicit, dependency-free package version only ever calls
these two - never the (considerably more complex) registration resource -
so it is intentionally not implemented here.
The service index bakes in a __BASE_URL__ placeholder for its "@id" fields,
since the host:port this fixture is actually reached on is only known once
tox-docker starts the container, not at image-build time (see
nuget-repo.nginx.conf). The flat container's own files never embed a URL,
so they need no such rewriting.
