  SERVICES (상품소개) PAGE
  biz-place.kr/services 의 실제 _services.css/_services.js를 그대로 받아 분석하여
  마크업 구조·박스 모델·rem 단위 체계와 동작을 재현했다.

  핵심 구조:
  - main.services-main 은 고정 높이(overflow:hidden)의 "창"이고, 그 안의
    div.container 가 카테고리 수 만큼 옆으로 긴 트랙이다. 트랙 맨 앞에는
    카테고리 1개 폭만큼의 빈 여백(padding-left)이 있어서, 첫 탭을 선택했을 때도
    "왼쪽으로 한 칸 이동"하는 동일한 로직을 탈 수 있게 되어 있다(홈 화면
    article.service 캐러셀과 동일한 트릭).
  - 원본은 데스크톱에서 퍼센트(-16.666% = -100vw), 모바일에서 vw 단위를 각각
    사용하지만 두 값은 수학적으로 동일한 결과(현재 idx * -100vw)이므로, 이
    프로젝트에서는 애매한 퍼센트 계산 대신 vw 단위 하나로 통일해 데스크톱/
    모바일 모두 재현했다.
  - 카테고리 탭바(section.select)는 원본에서 position:sticky(음수 top으로
    배너는 스크롤되어 사라지고 탭바만 고정되는 트릭)를 쓰지만, 이 프로젝트의
    style.css는 html,body에 overflow-x:hidden을 적용 중이라 일부 렌더링
    엔진에서 position:sticky가 정상 동작하지 않는 이슈가 있어(examples.css,
    notice.css와 동일 이슈) JS로 fixed 전환하는 is-stuck 방식으로 동일한
    룩앤필을 재현한다.

   height:100%로 고정하면 article.offsetHeight가 .services-main의 "현재"
