/* 사이트 바탕 스타일 — Bootstrap v4.3.1(MIT, https://getbootstrap.com) 에서 쓰는 것만 옮겨 왔다 (2026-10-07).
   원본 bootstrap.css(188KB)를 통째로 싣던 것을 뺐다. 남긴 것:
     - 요소 · 속성 선택자 규칙(reboot, 글자 기본값, [hidden] 등): 옛 사이트 CSS 전체가 이 바탕 위에 짜여 있다.
     - 템플릿 · 콘텐츠 · 스크립트에 실제로 나오는 클래스 42개의 규칙
       (active, alert, btn, btn-dark, btn-primary, card, card-body, card-footer, carousel, clearfix, close, col, col-lg-4, col-sm-10, col-sm-2, dropdown, dropdown-item, dropdown-menu, dropdown-toggle, float-right, focus, form-control, in, lead, mb-4, mb-5, ml-2, mt-2, mt-5, my-4, my-5, pb-4, pb-5, pt-4, pt-5, row, shadow, show, sr-only, table, text-center, text-danger)
   새로 쓰는 부트스트랩 클래스는 여기 없다. 필요하면 원본(/common/lib/bootstrap-4.3.1/bootstrap.css)에서 그 규칙만 옮겨 올 것.
   만든 도구: Installer/gen_base_css.py */
