   wd-subvisual — Sub Visual with Zoom-out Reveal + Text Slide-up
   --------------------------------------------------------------------------
   원본(진실원천): webdot-blueprints/00_global/sub-visual/_code/
                   a1_skenpulse_subvisual_zoom-reveal  (SK엔펄스)
   1:1 이식. 바꾼 것은 세 가지뿐이다.
     (a) 텍스트  — 페이지별 제목·영문 부제 (inc/nav.php 가 넣는다)
     (b) 이미지  — /assets/images/sub/*.jpg
     (c) 색·폰트 — --wd-* → --bmt-* 토큰
   수치(폰트크기·자간·transition·브레이크포인트)는 원본 그대로다.
   높이만 대표 지시로 줄였다 (629→480 / 모바일 365→300).

   원본에 없던 것 하나: 브레드크럼 항목의 드롭다운.
   기존 .route_wrap 바를 없애고 그 이동 기능을 여기로 흡수했다
   (안 그러면 같은 경로 텍스트가 화면에 두 번 나온다).

     배너를 1920x600 이상으로 다시 뽑으면 629 로 되돌려도 된다. */
