/* ============================================================
   feedback.css — TimeSave PDF feedback 페이지 레이아웃 스타일
   ------------------------------------------------------------
   [복사본] ts-vdl/vdl.css(구 site.css)의 사본입니다.
   ts-pdf의 도구 페이지는 pdf.css(도구 전용)를 쓰지만, feedback 페이지는
   사이트 레이아웃 클래스(.section/.form-card/.btn-primary/.card/.tag 등)를
   쓰는데 이는 pdf.css에 없고 vdl.css에만 있습니다.
   배포 시 도메인 분리(pdf=허브 / vdl=다운로더)를 고려해 폴더 밖(../ts-vdl/)
   참조 대신 pdf 폴더에 복사본을 둡니다. (link.css와 동일 원칙)
   ★ 스타일 수정 시 ts-vdl/vdl.css, ts-link/link.css 와 동기화할 것.
