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 Text

🎯 한 줄 통찰 (One-line insight)

w3-opacity is explicitly "designed to work with all colors" as a class, while text-shadow requires inline style attributes and doesn't have a dedicated W3.CSS class — meaning opacity effects are first-class framework citizens while shadow effects lean on raw CSS3, a distinction with a practical consequence: text-shadow doesn't work in IE9 and earlier, but nothing in the source suggests w3-opacity shares that limitation. [S1]

🧠 핵심 개념 (Core concepts)

  • w3-left-align / w3-right-align — text alignment classes. [S1]
  • w3-center — centers block-level content (not just text). [S1]
  • w3-wide — applies wider letter-spacing. [S1]
  • w3-opacity — reduces text opacity, works with any color. [S1]
  • Text shadow — CSS3, not a W3.CSS class — applied via inline style="text-shadow:1px 1px 0 #444"; NOT supported in IE9 and earlier. [S1]
  • Composability — opacity, shadow, bold, and color classes can all stack on one element simultaneously. [S1]

📖 세부 내용 (Details)

  • Alignment: <div class="w3-left-align"><p>Left aligned text.</p></div> / <div class="w3-right-align">...</div>. [S1]
  • Centering: <div class="w3-container w3-center"><h2>Centered Content</h2><img ...><p>Some centered text.</p></div>. [S1]
  • Opacity: <h2 class="w3-opacity">Text Opacity</h2>. [S1]
  • Shadow (inline style, no dedicated class): <h2 class="w3-blue" style="text-shadow:1px 1px 0 #444">Text Shadow</h2>. [S1]
  • Stacked effects: <h1 class="w3-text-yellow" style="text-shadow:1px 1px 0 #444"><b>Yellow Text + Shadow + Bold</b></h1>. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

  • text-shadow의 브라우저 제약: IE9 이하에서는 text-shadow가 동작하지 않는다는 점이 명시적으로 경고됨. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 투명도+그림자+굵게를 조합한 특수 텍스트 효과가 실전 활용의 대표 사례다. [S1]

💻 코드 패턴 (Code patterns)

Combining opacity, color, shadow, and bold on one heading (HTML):

<div class="w3-panel w3-blue">
  <h1 class="w3-text-orange" style="text-shadow:1px 1px 0 #444">
    <b>Orange Text + Shadow + Bold</b>
  </h1>
</div>
