"""CLI: replay every document in a Pro 3.x project and print a summary.

Usage:
    uv run python -m tools.epro2 data/raw/oshwhub/<project_uuid>
    uv run python -m tools.epro2 data/raw/oshwhub/<uuid> --dump-doc <doc_uuid>

Designed for sanity-checking the parser/replay against ESP-VoCat first;
later we'll diff replayed state against the editor-rendered ground truth.
