   - tray 폭과 max-height를 늘려 한국어 제목/설명 잘림을 줄였다.
   - title/body line-height와 spacing을 다시 잡아 임시 패널 느낌을 줄였다.
   - option row의 radius, padding, chevron 정렬을 보정해 더 차분한 recovery panel처럼 읽히게 했다.
+- `Pause / Break / Return`의 감정 톤 분리를 시작했다.
+  - `Return(break)`은 focus 복귀 tray와 같은 재질을 쓰지 않고, 더 부드러운 emerald tint release tone으로 분리했다.
+  - `Goal Complete`의 `잠깐 쉬기` 선택도 같은 release tone으로 연결했다.
+  - timer HUD도 break phase에서는 더 가벼운 emerald 계열 material로 바뀌어 pause/focus와 다르게 읽히도록 정리 중이다.
 - `/app`을 single-goal commitment gate로 다시 줄였다.
   - 2-step ritual setup을 제거했다.
   - current session이 있으면 `Resume` UI만 보여주고, `/space`로 이어가기만 제안한다.
