+# Syncs Crowdin translations from develop into version-16-hotfix,
+# filtered to only the strings present in hotfix's main.pot.
+#
+# Trigger: fires when version-16-hotfix's main.pot is updated — i.e., when
+# the POT update PR from generate-pot-file.yml is merged. At that point
+# hotfix's main.pot is authoritative, and this workflow fetches develop's
+# latest .po files (Crowdin translations) and merges them against it.
+#
+# The weekly schedule acts as a safety net to pick up any Crowdin translations
+# that arrived on develop between POT update cycles.
+#
+# POT file generation remains in generate-pot-file.yml (unchanged).
+# Maintain this file on develop only; it always acts on version-16-hotfix.
