// Writing through a nested struct field lvalue (`outer.inner.x = v`) and taking
// the address of a valid field both resolve the field pointer correctly: the
// lvalue-pointer path (lowerExprAsPtr) GEPs the matched field, never a silent
// field-0 default. Positive companion to the missing-field diagnostic (1145).
