/* ── 플로팅 버튼 — nc-scroll-top 과 나란히, 동일 사이즈 ─────────────────── */
/*
   안정성 노트:
   · width 를 직접 transition 하지 않음 — CSS 가 'auto' 로 보간할 수 없어
     호버 중 jitter / 떨림이 발생하는 원인이었음.
     대신 자식 라벨의 max-width + 부모의 padding/gap 만 transition → inline-flex 가
     자식 폭에 맞춰 부드럽게 늘어남.
   · border-radius: 22px 를 처음부터 캡슐 값으로 고정 (44px 높이일 땐 원형으로 보임)
     → transition 대상 1개 감소, 시각적 동일.
   · transform: translateY(-3px) hover 제거 — 호버 진입 순간 버튼이 위로 이동하면
     마우스가 버튼 아래 경계 근처에 있을 때 호버 진입↔해제 무한 루프(떨림) 발생.
     대신 box-shadow 강화로 elevation 표현.
