   독서토론 — 모임 책장(목록)과 모임 소개

   예전 화면은 코인 거래소의 상품 목록처럼 생겼다. 어두운 카드에 '경제/투자'
   '자기계발' 분류가 앞에 서 있었고, 들어가 보라는 말은 "+30P" 한 줄뿐이었다.

   이제는 그림책방의 모임방이다.
     - 누구와 읽는지(어린이 / 함께 / 어른)가 먼저 보인다.
     - 책 표지가 카드의 얼굴이다. 표지가 없으면 책 제목으로 표지를 그린다.
     - 모임 안의 글은 멤버만 보므로, 문 앞에는 "함께 나눌 질문" 하나와
       "지금 이야기가 오가고 있다"는 기척만 둔다. 누가 썼는지는 보이지 않는다.

   모임방 (hub) — 멤버가 들어와 함께 읽는 곳

   예전 모임방은 다른 메뉴와 딴 세상이었다. 대문자 딱지, 주황 버튼, 구역
   여덟 개가 한 줄로 넘쳐 들어오자마자 보는 '토론 게시판'은 화면 밖에 있었다.
   오른쪽 아래에는 글쓰기 버튼과 동행 헬리콥터가 겹쳐 떠 있었다.

   이제는 목록·소개와 같은 책방의 말과 색으로:
     - 머리에 책 표지와 "내 진도 · 다음 모임 · 함께 읽는 사람" 세 칸
     - 구역은 이야기부터. 들어오면 이야기가 먼저 보인다.
     - 쓰기 단추는 구역 제목 옆에 둔다. 떠 있는 것은 동행 헬리콥터 하나뿐.
     - 쓰는 칸은 휴대폰에서는 아래에서 올라오고, 넓은 화면에서는 가운데 뜬다.
