starter_build.py — DEPRECATED. Use starter_buyer.py or starter_capabilities.py.

This legacy script uses the old nested-keys YAML format (cover:, problem:,
module_a:, etc.). It is preserved so existing client YAMLs still build.

For new proposals, use:
  - starter_buyer.py        — named prospect, CTA, procurement step
  - starter_capabilities.py — reusable marketing asset, no prospect
  - starter_casestudy.py    — single engagement deep dive

The new starters use a flat `sections:` list with `type` + `intent` per page.
See references/narrative-planning.md for the consultant workflow and
references/content-rules.md for the intent-per-page rule.

Run (legacy format only):
  PYTHON="C:/Users/Andrew Krusell/AppData/Local/Programs/Python/Python312/python.exe"
  "$PYTHON" starter_build.py
