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 Case Study]]
## 🎯 한 줄 통찰 (One-line insight)
The source explicitly states "it does not matter for W3.CSS if you use `<div>` or `<header>`" — meaning every layout/color/size class taught throughout the tutorial works identically regardless of whether the developer chooses generic `<div>`s or HTML5 semantic elements (`<header>`, `<footer>`), so semantic markup is purely a developer preference with zero framework-level consequence. [S1]
## 🧠 핵심 개념 (Core concepts)
- **Incremental build order** — the case study deliberately layers concepts in sequence: plain HTML → wrap in `w3-container` → add color classes → add size classes → optionally swap to semantic elements → build a multicolumn grid → add navigation. [S1]
- **`w3-row-padding` + fraction classes** — the standard recipe for a responsive multicolumn layout: wrap columns in `w3-row-padding`, then use `w3-third`/`w3-quarter`/`w3-half` etc. inside. [S1]
- **Asymmetric column widths** — combining `w3-quarter` + `w3-half` + `w3-quarter` in one row produces a wider center column flanked by two narrower side columns, all still summing to a full row. [S1]
- **Framework-agnostic semantics** — `<div class="w3-container">` and `<header class="w3-container">` behave identically; W3.CSS classes attach to any element type. [S1]
## 📖 세부 내용 (Details)
- Minimal starting page: `<!DOCTYPE html><html lang="en"><title>W3.CSS Case</title><meta name="viewport" content="width=device-width, initial-scale=1"><link rel="stylesheet" href="https://www.w3schools.com/w3css/5/w3.css"><body><h1>My first W3.CSS website!</h1>...</body></html>`. [S1]
- Semantic equivalent of the same containers: `<header class="w3-container w3-light-grey"><h1 class="w3-jumbo">...</h1></header>...<footer class="w3-container"><p>This is my footer</p></footer>`. [S1]
- Three-column asymmetric layout: `<div class="w3-row-padding"><div class="w3-quarter">...</div><div class="w3-half">...</div><div class="w3-quarter">...</div></div>`. [S1]
## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- **div와 시맨틱 요소의 완전한 동등성**: "W3.CSS 입장에서는 div를 쓰든 header를 쓰든 상관없다"는 문장으로 시맨틱 마크업 선택이 순수히 개발자 취향임이 명시적으로 확인됨. [S1]
## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 이 챕터 자체가 지금까지 배운 모든 개념(컨테이너/색상/사이즈/그리드/네비게이션)을 실제 웹사이트 하나로 조립하는 종합 실전 사례다. [S1]
## 💻 코드 패턴 (Code patterns)
Asymmetric three-column responsive layout — wider center column (HTML/CSS):
```html
<div class="w3-row-padding">
<div class="w3-quarter"><p>Left column</p></div>
<div class="w3-half"><p>Wider center column</p></div>
<div class="w3-quarter"><p>Right column</p></div>
</div>
```
## ✅ 검증 상태 및 신뢰도
- **상태:** draft
- **검증 단계:** conceptual
- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
- **신뢰 점수:** 0.85
- **중복 검사 결과:** 신규 생성 (New discovery)
## 🔗 지식 그래프 (Knowledge Graph)
- **상위/루트:** [[W3.CSS Tutorial]]
- **관련 개념:** [[W3CSS Containers]], [[W3CSS Rows]], [[W3CSS Trends]], [[W3CSS Material]]
- **참조 맥락:** 처음부터 웹사이트를 만드는 종합 실습 챕터 — 머티리얼 디자인(Material) 챕터로 이어짐.
