/* 설정 (2026-10-31; dist/appearance-ui.js): one sheet for students and staff — 글씨체 (three font cards), 화면 색 (five
   swatches), for staff 학원 기본 글씨체, and at the bottom [화면 새로고침] [닫기]. Colours come only from the --t-* tokens
   (dist/theme.css and the theme files), so the sheet recolours with the choice; the swatch cards draw each set from inline --sw-* values
   (dist/theme-swatches.js). A switch changes colours only: transitions are off for the two frames it takes, so nothing
   cross-fades or moves (keyframe animations and reduced motion are untouched). Every target is at least 44 px.
   Review 2026-10-31: the sections scroll in .look-body and [화면 새로고침] [닫기] (.look-foot) stay at the sheet's bottom
   (a student's sheet fits a 412×915 phone without scrolling);
   a font card is drawn in its own face (data-font-sample on its copy), so a font tap never changes a card's height; the
   academy's change line and its two-line status keep their room while empty. Only 원장·매니저 see 학원 기본 글씨체
   (owner 2026-10-31: "3번 숨김"). */
