//! `Npm` implementation for Groovy.

// Groovy uses the dekobon grammar, which models all class-like bodies
// as `class_body` and flattens modifiers as direct children of the
// declaration. That rules out the Java macro, so an explicit impl is
// required. The `groovy_body_is_interface_like` and
// `groovy_has_explicit_public` helpers live in `metrics::npa` (Groovy
// section) so both impls share the same parent-kind and modifier
// heuristic.
