   2026-08 재수정(v2): 원본 사진 자체의 배경(회색조 데이터센터 통로)이 페이지의 순수 블랙(#03060c)보다
   밝아서, 사진 영역과 페이지 배경 사이에 미세한 사각 경계(고스트 프레임)가 남는 문제가 있었음.
   해결: (1) 실제 눈에 보이는 이미지 영역을 훨씬 좁게(전체 박스의 중앙 38%~46% 정도만 alpha=100%)
   잡고, 그 바깥으로는 아주 넓고 완만한 구간에 걸쳐 alpha를 0까지 서서히 낮추는 mask-image를 적용해
   "완전 투명(페이지 배경이 그대로 보임)"으로 귀결시킴 — 색을 덧칠하는 방식이 아니라 진짜 알파 0이므로
   어떤 대비 경계도 남지 않음. (2) 박스 자체를 넉넉하게 크게 잡아 페이드 구간에 충분한 여유 공간을 둠.
