+# Continuous "latest" builds track lotus HEAD, so only the newest submodule bump
+# needs to build. Cancel a superseded in-flight release: rapid lotus pushes would
+# otherwise queue several ~30-min Tauri builds back-to-back, and build-linux runs
+# on ubuntu-latest — the same runner pool as cinny's web CI — so the queue also
+# starves web CI/deploys. update-manifest only publishes release.json on full
+# success, so a cancelled run leaves the last good manifest untouched.
