"""Map an SEO findings.json → estimate-engine scope.json (service=seo, effort).

Stage 5 of ourdigital-presales-seo: keeps the SEO-specific mapping here; the engine
(96-ourdigital-estimate-engine) owns the costing. Then call:
  python <engine>/scripts/estimate.py --rate-card <engine>/references/rate_card.yaml \
    --catalog-dir <engine>/catalog --scope scope.json --out-dir <engagement>

Usage:
  python findings_to_scope.py --findings data/findings.json --out data/scope.json [--tier auto] [--seq N]
