/* 원장 소개 v7 · 약력 B안 확정본 — 큰 연도 색인 + 그 자리에서 커지는 사진 (2026-10-19 4차) · doctor.v7.html · doctor.v7.preview.html
   p-doc-v7-sb.css(2차 제안 · story-b 미리보기)를 바탕으로, 마우스를 따라다니던 카드(.sb-float)를 뺐다.
   줄: [큰 윤곽 연도] [제목 · 덧붙임] [사진]. 화면에 들어오면 괘선이 왼→오로 그어지고 연도가 금색으로 채워진다(p-doc.js [data-rv] → .is-in).
   사진은 항상 보인다. PC 마우스: 사진에 올리면 그 자리에서 2배로 커진다(오른쪽 가운데 기준, CSS :hover).
   모바일 · 터치: 사진을 누르면 글 폭만큼 커지고(오른쪽 위 기준, 배율 --zs 는 js/p-doc-v7-sb2.js), 다시 누르거나 다른 곳을 누르면 원래대로(.is-zoom). */
