   안내 문장의 줄바꿈을 '카드 너비'가 아니라 '읽는 사람'에게 맞추기 위한 것.
   내용을 바꾸지 않고 배치만 손볼 때 쓴다. 쓰는 쪽에서 골라 붙인다.

   · .txt-pretty   본문 문단(3줄 이상 갈 수 있는 것).
                   어절 묶음을 살리고 마지막 줄에 한 마디만 남는 것을 막는다.
   · .txt-balance  제목·짧은 안내(2줄 이하, 대개 가운데 정렬).
                   줄 길이를 고르게 맞춰 한 덩어리로 보이게 한다.
   · .txt-flow     문단(<p>) 사이 간격. 줄간격보다 눈에 띄게 넓어야
                   '다음 이야기'로 읽힌다.

   ⚠️ 본문에 .txt-balance를 쓰지 말 것. 줄 길이를 맞추려다 어절 묶음을 끊는다 —
      390px 실측: balance는 "설비 데이터가 저희 / 쪽으로", pretty는
      "설비 데이터가 저희 쪽으로 /" 로 갈렸다(order-status.html에서 확인).
   ⚠️ word-break:keep-all을 함께 두는 이유는 한국어 어절이 글자 단위로 잘리지
      않게 하기 위해서다. 둘 중 하나만 있으면 효과가 반쪽이 된다. */
