🎨 Palette: 필수 입력란 빈 값 오류 피드백 명확화

[seonghobae]

💡 What

• 대상 바이트(단일 및 일괄) 입력 필드가 비워졌을 때 단순히 에러를 없애는 대신 명시적으로 "This field is required."라는 텍스트 안내와 빨간색 강조를 표시하도록 수정했습니다.

🎯 Why

• 필수 입력 필드를 사용자가 비웠을 때 오류 메시지가 없으면 스크린 리더 사용자나 일반 사용자 모두 무엇이 문제인지 명확히 알기 어렵기 때문에 인지 부하를 줍니다.
• 명시적인 텍스트 안내를 통해 빈 입력값 상태임을 즉시 인지하도록 돕기 위함입니다.

📸 Before/After

• Before: 대용량 파일 변환 폼에서 대상 바이트 입력값을 지우면 힌트 텍스트 영역이 단순히 비워지고 aria-invalid 상태도 삭제되어 정상 상태인 것처럼 오해를 일으킴.
• After: 값을 지우면 "This field is required."가 표시되며 텍스트가 붉게 변하고 aria-invalid='true'가 부여되어 시각적, 청각적으로 필수 입력 누락 오류를 명확히 인지하게 함.

♿ Accessibility

• aria-invalid 상태를 true로 설정하여 스크린 리더 사용자에게 입력이 유효하지 않음을 명확히 전달합니다.
• setCustomValidity를 이용해 네이티브 HTML 폼 검증과 일치하는 텍스트 오류 메시지를 제공합니다.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 369b9

The change is intended to show clear required-field feedback, but the current script initialization can fail before validation handlers are registered, leaving users without the promised error feedback and potentially disrupting related form interactions. Merge should wait until the DOM initialization issue is fixed; the documentation mismatch should also be corrected.

DOM이 준비되기 전에 이벤트 리스너를 등록합니다.

batch_preset_buttons_container는 이후 마크업에서 생성되므로 Line 213의 getElementById(...) 결과는 null입니다. 브라우저는 null.addEventListener(...)에서 TypeError를 발생시키고 스크립트 실행을 중단합니다. 따라서 Line 260-263과 Line 295-298의 빈 값 처리기를 포함한 이후 이벤트 리스너가 등록되지 않습니다.

<script>를 일괄 폼 뒤로 이동하거나, DOMContentLoaded 이후에 모든 DOM 의존 초기화를 실행해 주세요. 현재 관련 테스트는 HTML 문자열만 검사하므로 이 런타임 경로를 검증하지 않습니다.

required-error and aria-invalid behavior, removing any conflicting duplicate
explanation. Update .jules/palette.md lines 1-3, specifically the guidance
around setCustomValidity and aria-invalid removal, to match the new behavior or
explicitly scope it to the historical behavior.
