   오브젝트 상태 — `.st`
   레코드의 «상태» 를 나타내는 유일한 컴포넌트. 위 `.badge-*` 는 «분류(Tag)» 로만
   남기고, 상태는 전부 이쪽으로 옮긴다.

   왜 상자가 없는가 — 실물 아홉 곳을 촬영해 대조한 결과, 모든 상태를 진한 색으로
   채우는 곳은 하나도 없었다. SAP Fiori Object Status 는 명시적으로
   「semantically colored text-only option on its own」 을 권장하고,
   채운 판(inverted)은 「if the information is crucial for the user's actions」
   일 때만이라고 못박는다. Adobe Spectrum 은 「Color alone is not enough」 라
   낱말을 필수로 둔다.

   규칙
     ① 상태는 «낱말» 이다. 상자는 기본값이 아니다.
     ② 색은 «단계를 열거» 하지 않는다. «조치가 필요한가» 를 말한다.
     ③ 중립은 색이 없다. 목록의 대다수가 중립이라 목록이 조용해진다.
     ④ 조치가 필요한 둘(action·back)에만 아이콘을 단다 — 회색조·색약에서 그 둘이
        형태로 갈린다. 전부에 달면 그 효과가 사라진다.
     ⑤ 채운 판(`--solid`)은 화면당 하나 — 「이 문서의 지금 상태」.

   대비 실측(흰 바탕) — 중립 7.01 · 진행 7.04 · 완결 6.98 · 조치 6.98 ·
   되돌아옴 6.99 · 종료 4.61. 채운 판 위 흰 글자 4.59~4.61. 전건 WCAG AA.
   신규 색 0 — 전부 §1 램프의 11단(글자)과 9단(면)이다.

     `rnd.css` 정의로 쓰고 있어, 전역에 풀면 그쪽 글자를 말없이 바꾼다.
   ★ 색은 «숫자와 아이콘»에만 얹는다 — 배포된 대시보드 타일(`.dv-stat-c1`)이
     쓰는 방식이다. 카드 5장을 통째로 칠하면 전부가 동시에 소리를 질러
     「지금 봐야 할 칸」이 사라진다.
