// Groovy uses the dekobon grammar, which models class/interface/trait/
// annotation-type/record bodies as a single `class_body` node and
// flattens modifiers as direct children of the declaration (the
// `_modifier` rule is hidden — no `Modifiers` wrapper). That rules out
// the Java macro, so an explicit impl is required.
//
// `def field` at class scope parses as a `FieldDeclaration` with `Def`
// in the modifier slot and no `Public`, so it's correctly excluded from
// `class_npa` unless explicitly annotated `public` — consistent with
// Groovy's access semantics (we conservatively follow Java).
