/*
 * S/W 프로그램 소개 페이지(sw_store/info) 전용 디자인 CSS.
 *
 * 예전에는 이 CSS를 각 프로그램 소개 페이지("페이지 관리")의 content 안에 <style> 태그로
 * 직접 넣어뒀는데, TinyMCE 에디터가 저장할 때 <style>/<link> 태그를 body 콘텐츠에서
 * 유효하지 않은 요소로 보고 통째로 제거해버려서, 관리자가 텍스트를 한 글자만 고쳐도
 * 디자인이 전부 날아가는 문제가 있었다. 그래서 CSS를 DB content에서 완전히 분리해
 * 정적 파일로 빼고, sw_store/info.php 에서 <link>로 직접 불러오도록 했다.
 * (관리자는 이제 각 페이지의 class="apm-landing/skitch-landing/yt-landing" 래퍼와
 * 그 안의 구조만 건드리지 않으면, 본문 텍스트를 자유롭게 수정해도 디자인이 유지된다.)
