+{% comment %}
+YYC MARK:
+The base messages file pairing (the official full translation that provides
+the language identity) is derived from MetaGlot's best-effort conversion of
+the PO language tag to the conventional Inno Setup language name (lang.lang).
+The English source language maps to "Default" and languages unknown to
+MetaGlot convert to nothing; both fall back to "compiler:Default.isl" and
+inherit the English language identity, so pair such a language with its base
+file explicitly (e.g. via a "case" on "lang.name") when adding one. The
+incremental custom messages file is named after the conventional name (or
+the PO language tag when no conventional name exists); keep it in sync with
+the "--isl-path" argument in CMakeLists.txt.
