# Single-OS job that sets up the Nim/Nimble toolchain + cached deps, then runs
# one shell command across the Nim-version matrix. Shared by the ci.yml jobs
# whose only difference is the command they run (check-bindings, the submit
# scaling gate, …). Multi-OS / sanitizer matrices live in test.yml /
# tests-sanitized.yml instead.
