  # -------------------------------------------------------------------------
  # 1) Compose UI test — verifies the composable tree renders (login screen)
  #    under the dev classpath. Catches missing string resources, broken
  #    composables, and basic dependency-graph issues.

  # -------------------------------------------------------------------------
  # 2) Release .deb build + launch — builds the ProGuard'd, jlink'd .deb
  #    package, installs it, and verifies the process stays alive for 10s.
  #    Catches ProGuard stripping (JNI, reflection), missing jlink modules
  #    (java.management, java.prefs), and native lib bundling issues.
