      # Trade-off: this task runs for both `task desktop:dev` and
      # `task desktop:build`, so production bundles also ship mode-644

      # `other` bit is `r--` either way, and on macOS code signing is the
      # real integrity check) and on Windows the DOS read-only attribute
      # isn't load-bearing for the bundled JDK. If we ever need strict
      # 444 in production, split the chmod into a dev-only step and have
      # `desktop:build` run `jlink:clean` first to force a fresh build.
