+      CFBundleLocalizations is generated from the metadata localization languages (the metaglot
+      "langs" list), while this field by definition describes the application's language
+      availability. This deviation works around an upstream Qt bug: since the Qt 6.7.0 refactor,
+      the CMake function _qt_internal_store_languages_from_ts_files_in_targets loses the parsed
+      TS language codes (a missing list(APPEND)), so Qt's own CFBundleLocalizations generation
+      yields an empty list. Consistency between the metadata languages and the application
+      languages is maintained manually at release time.
+      TODO: drop this workaround and let Qt generate CFBundleLocalizations itself once the
+      upstream bug is fixed and the fix ships in the CI toolchain.
