/* ── Open Design Lab — Social (Instagram) 탭 ────────────────────────
 * /instagram 주소에서 social.js 가 그리는 화면.
 * 썸네일이 깊이가 다른 세 겹의 층 위에 떠 있고(구름), 마우스·스크롤에 따라
 * 층마다 다르게 밀리는 패럴랙스. 호버하면 살짝 커지며 앞으로 나오고,
 * 클릭하면 인스타그램 공식 임베드가 모달로 열린다.
 * 이 탭은 항상 다크(dark-mode.js 가 /instagram 을 다크 전용 라우트로 처리 → html.dark 고정).
 * 사이트의 다크는 전체 invert(1) 이므로, 여기 색은 전부 '반전되기 전' 값으로 적는다.
 *   보이는 색       → 적는 색
 *   검정 #0b0b0e    → #f4f4f1
 *   ODL 블루 #2b66ff → #d49900
 *   흰 글자         → #000 계열
 * (img·iframe 은 전역 규칙으로 재반전되어 원래 색으로 보인다) */
