defmodule Kreuzberg.DocumentStructure do

  Top-level structured document representation.

  A flat array of nodes with index-based parent/child references forming a tree.
  Root-level nodes have `parent: None`. Use `body_roots()` and `furniture_roots()`
  to iterate over top-level content by layer.

  # Validation

  Call `validate()` after construction to verify all node indices are in bounds
  and parent-child relationships are bidirectionally consistent.
