 * 화면 맞춤 원칙 (Round 5)
 * - 화면 높이 = --vh (100dvh, 미지원 브라우저는 JS가 넣는 --app-h, 그다음 100vh).
 * - 대시보드는 세로 스크롤 없이 한 화면: 헤더/매트릭스/계측/하단 표시등을 fr 비율로 나누고,
 *   각 영역(.board-slot)은 size 컨테이너라 안의 셀·글자가 영역의 폭·높이 중 작은 쪽에 맞춰진다.
 * - 설정·알림은 헤더 고정, 목록만 내부 스크롤. 로그인만 페이지 스크롤 허용(키보드 대응).
 * - 노치·홈 인디케이터: env(safe-area-inset-*).
