"""Export the deliverable notebook as LLM-readable report sources.

Executes the notebook fresh (widget seeds — the mock scenario, or
whatever seeds you edit in), then writes both formats to exports/:

  exports/diagnostic.html  — human-reviewable, tables render
  exports/diagnostic.md    — leanest LLM input

Plotly figures export as JavaScript an LLM cannot read; the notebook's
machine-readable appendix section carries every number behind them.

Run from the project root:  python scripts/export_report.py [name-filter]
An optional argument exports only notebooks whose filename contains it.
