build_deck.py — 템플릿 스타일 + 제안서 콘텐츠(JSON) → proposal.pptx 생성.
deck-designer가 프로젝트별 콘텐츠 JSON만 주입해 재생성 가능한 골격 스크립트.
디자인 시스템(색/폰트)·선 아이콘(SVG는 사전 PNG/EMF 변환 또는 도형)·도식은 deck-designer가 채운다.

사용: python build_deck.py --content content.json [--template template.pptx] --out proposal.pptx
content.json 예:
{
  "design": {"primary":"1F4E79","accent":"2E9BD6","text":"222222","font_ko":"맑은 고딕"},
  "slides": [
    {"layout":"title", "title":"○○시스템 구축 제안서", "subtitle":"제안사 / 2026"},
    {"layout":"section", "title":"1. 사업 이해"},
    {"layout":"content", "title":"추진 전략", "bullets":["...","..."]},
    {"layout":"diagram", "title":"추진 체계도", "note":"도형은 deck-designer가 보강"}
  ]
}
의존: pip install python-pptx · 외부 호출 없음.
