Overview

Orchestrates the snapshot pipeline:

page.body  ──Extractor──▶  [nodes]
           ──Annotator──▶  [entries with ref + fingerprint]
           ──Serializer─▶  wire-shape array

Each stage is independently testable. Inject alternates via the keyword args for tests that want to isolate one stage.
