Antigravity Agent c24165b8bc refactor(topics): 멀티 에이전트용 지식 재편 — _Common(공통 기본기) + Domain_* 구조
에이전트 8종(대화형/프로그래머 C·S/디자이너/설계자/기획자/QA/PD/PM)에게
[공통 기본 능력 + 롤별 Specialty] 2층으로 지식을 주입하기 위한 재분류.
문서 내용·포맷은 무수정, 폴더 이동만 (6,372개 문서 수 보존 확인).

- Topic_Programming → Domain_Programming (내부 구조 보존)
- Topic_Graphic → Domain_Design
- Topic_Business → Domain_Product
- Topic_General → Domain_General
- _Common 신설: Math(구 Topic_Math_Specialty), Reasoning(구 General/From_Thinking & Reasoning),
  Reasoning_Creativity(구 General/From_창의성), Communication(Poetic_Blog_Writing + From_writing)
- 타 도메인의 From_* 폴더는 유지 (출처 표기일 뿐, 이미 도메인에 맞게 분류된 문서)
- 빈 폴더 정리 (memory/procedures)
- 에이전트→폴더 매핑은 workspace의 .astra/agent-knowledge-map.json (9개 에이전트)

W3CSS Cards

🎯 한 줄 통찰 (One-line insight)

w3-hover-shadow can turn ANY plain element into something that behaves like a card purely on mouse-over — the source notes it uses "the same style as w3-card-4," meaning you can defer the card-like shadow effect to a hover interaction instead of applying it permanently, without needing a separate shadow value. [S1]

🧠 핵심 개념 (Core concepts)

  • w3-card — alias for w3-card-2 (2px bordered shadow). [S1]
  • w3-card-2 / w3-card-4 — containers with 2px/4px shadow depth respectively. [S1]
  • Composable with headers/footers — a card can contain its own <header>/<footer> with w3-container, creating distinct sections inside one card. [S1]
  • w3-hover-shadow — adds the card-4 shadow effect only on hover, making any plain element look card-like on mouse-over. [S1]
  • Photo cards — an <img> combined with a w3-container caption div inside a w3-card-4 wrapper. [S1]

📖 세부 내용 (Details)

  • Basic card: <div class="w3-card"><p>w3-card</p></div>. [S1]
  • Sectioned card with header/footer: <div class="w3-card-4"><header class="w3-container w3-blue"><h1>Header</h1></header><div class="w3-container"><p>Lorem ipsum...</p></div><footer class="w3-container w3-blue"><h5>Footer</h5></footer></div>. [S1]
  • Photo card: <div class="w3-card-4"><img src="img_snowtops.jpg" alt="Alps"><div class="w3-container w3-center"><p>The Italian / Austrian Alps</p></div></div>. [S1]
  • Hover-only shadow: <div class="w3-green w3-hover-shadow w3-center"><p>Hover over me!</p></div>. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 친구 요청 카드, 날씨 위젯 카드 등 header+container+footer 조합으로 구성된 복합 카드가 실전 UI 패턴의 대표 사례다. [S1]

💻 코드 패턴 (Code patterns)

Card-like shadow only on hover (HTML):

<div class="w3-green w3-hover-shadow w3-center">
  <p>Hover over me!</p>
</div>
