docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합

이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영.

- Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들
  (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거.
- Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/
  Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/
  Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이
  존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존).
- Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/
  JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동.
- 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리.
- Topic_Programming 최종 문서 수: 2784 → 3985.

+# [[W3CSS Material Design]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+W3.CSS has no dedicated "Material Design mode" — achieving a Material look is entirely a matter of COMPOSING existing general-purpose classes already taught in earlier chapters (`w3-card` for paper-like elevation/shadow, `w3-bar`/`w3-sidebar` for the status/tool/tab bars, color classes for theming), confirming the framework's overall design philosophy of reusable primitives over named design-system modes. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Material Design origin** — designed by Google in 2014, later adopted across many Google applications; uses paper-and-ink metaphors with realistic shadows and hover effects. [S1]
+- **Card-based content** — Material's signature "card" pattern is achieved with the SAME `w3-card` classes covered in the Cards chapter, not a Material-specific class. [S1]
+- **Layered navigation bars** — a Material-style app UI is built from multiple stacked `w3-bar` elements (status bar, toolbar, tab/search bar), each independently simple, combined ("All Together Now") into one cohesive header. [S1]
+- **Color themes** — Material's colorful look is achieved via W3.CSS's color-theme system (cross-referenced to a later Color Themes chapter), not a Material-only palette. [S1]
+
+## 📖 세부 내용 (Details)
+- The chapter's "All Together Now" example stacks a status bar, a toolbar with a title, and a tab bar with links into a single composite navigation header — each layer built from the same `w3-bar` primitive. [S1]
+- Colorful Material-style cards (Sport/News/Music) reuse the standard card structure (image + text block) with distinct color classes per card. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- 현재까지 발견된 모순 사항 없음 (No contradictions found in available sources).
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 상태바+툴바+탭바를 층층이 쌓아 하나의 머티리얼 스타일 헤더를 만드는 조합이 실전 모바일 앱 UI 구성의 대표 사례다(다음 Mobile 챕터에서 실제 앱으로 확장됨). [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Stacking bars to build a layered Material-style navigation header (HTML/CSS):
+```html
+<div class="w3-bar w3-black">12:30</div>
+<div class="w3-bar w3-teal w3-large">Title</div>
+<div class="w3-bar w3-light-grey">
+  <a href="#" class="w3-bar-item w3-button">Link 1</a>
+  <a href="#" class="w3-bar-item w3-button">Link 2</a>
+</div>
+```
