docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동

최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치. 콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서 전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한 업데이트0615/무제 3.canvas 뿐).

+# [[W3CSS Fonts]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+W3.CSS uses TWO different default fonts, not one — Verdana for body text (better letter spacing, readable) but Segoe UI specifically for headings (narrower spacing, fits more characters) — meaning the "default font" question has different answers depending on whether you're styling body copy or a heading. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Default fonts** — Verdana (body), Segoe UI (headings, narrower spacing). [S1]
+- **Four built-in font classes** — `w3-serif`, `w3-sans-serif`, `w3-monospace`, `w3-cursive`. [S1]
+- **Web-safe sans-serif** — Arial (safest, 99.8%/98.7% Win/Mac), Helvetica (100% Mac, only 7.3% Windows), Verdana, Geneva, Tahoma, Trebuchet MS — each with a suggested fallback. [S1]
+- **Web-safe serif** — Times New Roman (with Times fallback), Georgia. [S1]
+- **Monospace** — Courier New (safest), Lucida Console (no Mac support) with Monaco as its cross-platform fallback. [S1]
+- **No universally safe handwriting font** — `w3-cursive` is the recommended fallback since none exists natively. [S1]
+
+## 📖 세부 내용 (Details)
+- Global font override: `body, h1, h2, h3, h4, h5, h6 { font-family: Arial, Helvetica, sans-serif; }`. [S1]
+- Font class usage: `<p class="w3-serif">...</p>`, `<div class="w3-monospace">...</div>`, `<div class="w3-cursive">...</div>`. [S1]
+- Cross-platform monospace fallback chain: `font-family: "Lucida Console", Monaco, monospace;` — Monaco fills in where Lucida Console (no Mac support) fails. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **본문과 제목의 기본 폰트가 다름**: Verdana(본문)와 Segoe UI(제목)가 서로 다른 목적으로 사용된다는 점이 강조됨. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — Lucida Console+Monaco 폴백 체인이 플랫폼 간 monospace 폰트 호환성 확보의 대표 실전 사례다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Cross-platform monospace font fallback (CSS):
+```css
+body, h1, h2, h3, h4, h5, h6 {
+    font-family: "Lucida Console", Monaco, monospace;
+}
+```
+
