        Zero runtime dependencies. Test-scope JUnit 5 only.

        Local dev:
          mvn -q package
          mvn -q install                       # publishes to ~/.m2 for downstream tests
          mvn -q test

        Release (tag push triggers .github/workflows/release.yml):
          mvn -B -P release deploy             # staging via central-publishing-maven-plugin

        Required Maven Central setup (one-time per host):
          - com.submillisecond namespace verified at https://central.sonatype.com
          - GPG key + passphrase wired into the runner via secrets
          - OSSRH_USERNAME / OSSRH_TOKEN secrets set on the GitHub repo
