   ---------------------------------------------------------------------------
   원칙 세 가지.
   1) 웹폰트를 쓰지 않는다. 시스템 한글 글꼴로 그리면 다운로드 대기도,
      글자가 나중에 바뀌며 흔들리는 일도 없다. 첫 화면이 가장 빨리 뜬다.
   2) 사진이 아직 없다. 빈 이미지 자리를 두는 대신 분야별 색과 타이포로
      화면을 채운다. 나중에 사진이 들어와도 같은 자리에 그대로 얹힌다.
   3) 애니메이션은 합성(compositor)만 건드리는 것으로 제한한다.
      transform 과 opacity 외에는 움직이지 않는다.
