+# Runs ONLY on Gitea (GitHub ignores .gitea/workflows), in the private Builds
+# repository. Gitea is master; GitHub is a mirror and a release surface.

+# Unlike the Windows lane, which builds a static toolchain of its own through
+# contrib/depends, the x86_64 AppImage links against the host's Qt6. Those
+# dependencies are owned by such-fleet (roles/wowlet_build_host) rather than
+# installed here: a workflow that apt-installs needs sudo on a shared runner and
+# makes the build host's contents a property of whichever job ran last.
+#
+# Dispatch-only. The runner is capacity 1 and shared with the fleet gates.
