 * that gathers warnings for one document's `ast.warnings`. Returning the caller's own object
 * would attach that state to an object they may reuse, so a second parse would append its
 * warnings to the first document's already-returned AST, and each parse would retain the
 * previous one's state for as long as the config lived.
 *
 * Only the configuration containers are copied. Callbacks and `abortSignal` keep their
 * identity, since a copy of an `AbortSignal` would no longer be tied to its controller.
