/**
 * [Purpose] : 홈 화면의 지도 위 컨트롤(버튼, 배지, 범례) 및 하단 필터 섹션(태그, 유형, 날짜)의 세부 스타일을 정의하는 스타일시트
 * [Dependencies] : index.html (템플릿), home_data.js (필터 적용), home_ai.js (AI 검색 UI), Kakao Maps SDK
 * [Data Flow] : N/A (상수 및 스타일 정의)
 * [Side Effects] : 
 *   - UI (DOM) 스타일링: 지도 위 버튼(.map-btn), 모드 전환 배지(.mode-badge), 범례(.legend-box) 및 각종 필터 칩(Tag/Type Chip) 제어
 *   - 상태 피드백: 필터 변경 시 '적용' 버튼에 .dirty 클래스를 추가하여 시각적 강조(.ctrl-apply-btn.dirty)
 * [Constraints / Notes] : 
 *   - 상단 컨트롤: .map-top-left는 absolute 포지셔닝으로 지도 왼쪽 상단에 고정됨
 *   - AI 입력창: .ai-prompt-input은 resize: none 속성으로 사용자의 임의 크기 조절을 차단함
 *   - 필터 칩: .tag-chip 및 .type-chip은 .selected 클래스 여부에 따라 배경색과 폰트 굵기가 변경됨
