사용자 경험과 접근성 향상을 위해 대시보드 헤더의 투박한 네이티브 `<input type="file">` 요소의 디자인을 개선했습니다.
시각적으로 어색했던 네이티브 파일 입력을 숨기고(`.sr-only`), 기존 디자인 토큰과 동일한 스타일을 적용한 커스텀 "Upload report" 버튼(`<button>`)을 통해 이벤트를 프록시(proxy)하도록 구현했습니다. 이로 인해 SPA(Single Page Application) 헤더 디자인의 일관성이 향상되었으며 불필요한 시각적 노이즈가 제거되었습니다.

수정 사항:
- `scanner/dashboard/index.html` 내 헤더의 `<input type="file">`에 `sr-only` 및 `aria-hidden` 클래스 적용하여 시각적 숨김 처리
- 스타일이 적용된 `header-browse` 프록시 버튼 추가
- `header-browse` 버튼 클릭 시 네이티브 파일 입력의 `click()` 메서드를 호출하는 이벤트 리스너 추가
- `tests/test_dashboard_core.py`의 테스트 코드 변경 (접근성 검증 관련 assertion 업데이트)
- `.jules/palette.md` 파일에 네이티브 파일 입력 프록시 처리 시 UX 및 a11y 고려사항에 대한 학습 내용 추가

 ## 2026-08-06 - Dashboard status semantics
 **Learning:** A loaded report with zero findings is a successful security outcome, not the same state as missing input. Announcing the same update through multiple live regions can also create duplicate screen-reader output.
 **Action:** Keep one pre-existing polite, atomic status region; separate unloaded and clean-report states with an explicit loaded sentinel; and centralize English finding-count grammar in one formatter.

+## 2026-08-06 - Proxying Native File Inputs
+**Learning:** Native `<input type="file">` elements are notoriously difficult to style consistently across browsers and look out-of-place in polished header navigation bars. However, completely replacing them can break accessibility or violate CSP if done incorrectly.
+**Action:** Always replace visually unappealing native file inputs with a styled proxy `<button>` (using existing design system tokens like `class="primary-action"` or inline styles based on `--surface` and `--border`) and hide the actual input using `.sr-only` and `tabindex="-1"`. Connect the button to the input securely using a JavaScript `.addEventListener('click', ...)` to trigger `.click()` on the input.
