   - AX Agent 내부 설정 개발자 탭의 `워크플로우 시각화`, `전체 호출·토큰 합계 표시`, `감사 로그` 토글이 누르자마자 꺼지는 문제를 수정했다. 각 토글의 변경 이벤트를 연결해 즉시 저장되도록 보정했다.

   - AX Agent 내부 설정 `도구 훅 실행 타임아웃`과 `등록된 훅` 영역에서 잘림이 보이던 레이아웃을 보정했다. 슬라이더/값 배지 컬럼 폭과 `훅 추가` 버튼 최소 폭을 넉넉히 늘려 텍스트와 컨트롤이 서로 밀리지 않게 정리했다.

+  - AX Agent 테마를 다시 점검해 기존 `Claw / Codex / Slate` 외에 `Nord`, `Ember` 2종을 추가했다. `Nord`는 차분한 블루그레이 업무형 톤, `Ember`는 따뜻한 앰버 문서 작업 톤으로 구성했다.
+  - 내부 설정 `테마 스타일` 카드에서도 새 프리셋을 바로 선택할 수 있게 연결했고, `system / light / dark` 모드 조합으로 같은 방식으로 적용되도록 정리했다.
