// `declare const __VERSION__: string` — the bundler-define pattern: the
// ambient global exists only as a type. Running the SOURCE (Node and
// scriptc alike) has no define step, so a read throws the catchable
// ReferenceError "<name> is not defined" at the access — name, message,
// and instanceof pinned.
