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 Buttons

🎯 한 줄 통찰 (One-line insight)

W3.CSS's philosophy is that ANY element can be a button, not just <button> — the tutorial explicitly shows <input type="button"> and <a> tags gaining identical button behavior from the same w3-button/w3-btn classes, and even states "Any div, header, footer or other containers can be a w3-button" with a live image demonstrating a picture styled as a clickable button. [S1]

🧠 핵심 개념 (Core concepts)

  • w3-btn — rectangular button with a SHADOW hover effect; default color black. [S1]
  • w3-button — rectangular button with a GRAY hover effect; default color inherits from parent (v4+). [S1]
  • w3-bar — horizontal container for grouping buttons (navigation menus). [S1]
  • w3-bar-item — removes the gap between grouped buttons inside a w3-bar. [S1]
  • w3-block — full-width (100%) button. [S1]
  • w3-circle — circular button. [S1]
  • w3-ripple — click-triggered ripple animation effect. [S1]
  • w3-disabled — CSS-only disabled appearance (opaque, "no parking sign" cursor) for elements that don't support the native disabled attribute (like <a>). [S1]
  • w3-show-inline-block — lets multiple w3-bar groups sit on the same line. [S1]

📖 세부 내용 (Details)

  • Any element as a button: <input class="w3-button w3-black" type="button" value="Input Button"> <button class="w3-button w3-black">Button Button</button> <a href="..." class="w3-button w3-black">Link Button</a>. [S1]
  • Grouped, gapless bar buttons: <div class="w3-bar"><button class="w3-bar-item w3-button w3-black">Button</button>...</div>. [S1]
  • Full-width with custom width via inline style: <button class="w3-button w3-block w3-black" style="width:30%">Button</button>. [S1]
  • Disabled link (since <a> has no native disabled attribute): <a class="w3-button w3-disabled" href="...">Link Button</a>. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

  • 모든 요소가 버튼이 될 수 있음: div, header, footer, 심지어 이미지까지도 w3-button/w3-btn 클래스로 버튼처럼 동작할 수 있다는 점이 명시적으로 시연됨. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — w3-bar-item으로 간격 없이 버튼을 묶어 내비게이션 바를 만드는 것이 실전 UI 구성의 대표 사례다. [S1]

💻 코드 패턴 (Code patterns)

Gapless button bar acting as a navigation menu (HTML):

<div class="w3-bar w3-black">
    <button class="w3-bar-item w3-button">Button</button>
    <button class="w3-bar-item w3-button">Button</button>
    <button class="w3-bar-item w3-button">Button</button>
</div>
