+# DISABLED: the Flutter reader apps are currently dysfunctional and must not be
+# released until the underlying issues are fixed. The automatic tag-push trigger
+# is intentionally removed so version tags (e.g. v0.7.3) do NOT build or publish
+# mobile release artifacts. The workflow is retained under workflow_dispatch so
+# maintainers can still run it manually while validating a fix; restore the
+# "push: tags" trigger below to re-enable automatic releases.
