+name: Enforce Issue Templates
+
+# Every issue created through one of our issue forms (report_issue.yml,
+# request_feature.yml, request_plugin.yml) automatically gets that
+# template's `labels:` applied at creation time. An issue with no labels
+# at all at creation therefore skipped every template - e.g. it was
+# opened via the API/CLI, or a deep link like
+# `/issues/new?template=...` fell back to a blank issue. GitHub only
+# enforces required template fields inside its own web form, so this is
+# the closest we can get to enforcing the templates after the fact.
