"""부여군 N(저작물 유형) + O/P/Q(공공누리) 전수 재판정.
사용자 검수(3~37행)를 정답으로 검증 후 38행~ 적용.

핵심(부여 buyeo 템플릿 특성):
- KOGL 마크는 게시판 '상세글'의 `div.gnuri_layer > .codeView01 > img[src=/_module/gnuri/images/img_opentypeNN.png]`
  + kogl.or.kr/info/licenseTypeN.do 링크. **본문(#txt) 바깥**이라 기존 phase234가 놓침.
- 상세 URL = `?mode=V&no=...`.
- 게시판은 글마다 유형 다를 수 있음 → O = **첫 마크 글의 유형**(사용자 컨벤션: 01030502 글1=1유형 → O=1유형).
- N 이미지: 장식/공통UI(file_icon·see_btn·btn_page·/skin/·/common/·ico/btn/bg) + KOGL 마크 제외.
  지도/PDF iframe = 이미지. 게시판 M=0 = 없음. 실제 업로드 사진만 이미지.

사용: python -X utf8 _buyeo_rejudge_NO.py --validate   # 3~37 사용자값과 비교
      python -X utf8 _buyeo_rejudge_NO.py --write       # 38행~ 기입(백업)
