def initialize(opts = {})
  @type_filter = opts[:type]&.downcase
  @tag_filter  = opts[:tag]
  # Collect schema-driven attribute filters from all element classes.
  @attr_filters = _collect_attr_filters(opts)

def apply(elements_hash)
  elements_hash.select { |_, el| !el.is_a?(::MPS::Elements::MPS) && _match?(el) }
end

#apply_for_tree(elements_hash) ⇒ Object

Applies filters while preserving the full tree structure including @mps containers. Used by the presenter’s tree renderer so group headers are correctly suppressed when all their children are filtered out.
