# Produces versioned distributables for ALL targets a host can build, into a GitHub Release.
# Each target verifies its own required artifacts. Publishing uses every successful target, so
# apk/exe are not held hostage by Linux-only packaging dependencies.
#   linux (deb/rpm/AppImage) + iso                  -> debian:trixie
#   android (apk)                                   -> ubuntu-latest
#   windows (exe)                                   -> windows-latest
#   macos   (dmg)                                   -> macos-latest
# NOTE: iOS cannot be produced — the project has no iOS Kotlin target (commonMain uses
#       JVM-only libs); there is no iOS step.
