Antigravity Agent e9cbf23ab5 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 Mobile

🎯 한 줄 통찰 (One-line insight)

A "mobile app" list layout (avatar + title + description per row) is built from the SAME w3-cell-row/w3-cell pair covered in the Cells chapter — meaning this entire chapter's app UI is really a targeted APPLICATION of two earlier chapters (Cells for row layout, Versions' Pro build for lean file size) rather than introducing any mobile-specific classes. [S1]

🧠 핵심 개념 (Core concepts)

w3pro.css for mobile — explicitly recommended here because its smaller, colorless file size suits performance-sensitive mobile app contexts (direct callback to the Versions chapter). [S1]
Movie-list layout via cells — w3-cell-row containing one w3-cell for an avatar image and another w3-cell w3-container for title+description, per list item. [S1]
w3-circle — rounds an image into a circle, commonly used for avatar-style app icons. [S1]
w3-text-theme — a theme-aware text color class that adapts automatically when a color theme stylesheet is swapped in. [S1]
Slide-in side navigation with an avatar header — combines w3-sidebar, a colored header block containing a circular avatar, and a close button (w3-display-topright), reusing the Sidebar chapter's open/close JS pattern verbatim. [S1]
Fixed header/nav/footer — w3-top on both a <header> and <nav> simultaneously, plus w3-bottom on the footer, for a fully pinned app chrome. [S1]

📖 세부 내용 (Details)

App-style list row via cells: <div class="w3-cell-row"><div class="w3-cell"><img src="img_avatar.jpg"></div><div class="w3-cell w3-container"><h3>Frozen</h3><p>The response to the animations was ridiculous.</p></div></div>. [S1]
Theme-aware avatar and text: <img class="w3-circle" src="img_avatar.jpg" alt="avatar"><h3 class="w3-text-theme">Frozen</h3>. [S1]
Side navigation reusing the Sidebar chapter's open/close pattern: function openSidebar() { document.getElementById("mySidebar").style.display = "block"; } function closeSidebar() { document.getElementById("mySidebar").style.display = "none"; }. [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 — 이 챕터 전체가 Cells/Sidebar/Versions 챕터에서 배운 클래스를 재조합해 실제 모바일 앱 UI를 만드는 종합 실전 사례다. [S1]

💻 코드 패턴 (Code patterns)

A movie-list row using cells — the same pattern from the Cells chapter, applied to app UI (HTML):

<div class="w3-cell-row">
  <div class="w3-cell">
    <img src="img_avatar.jpg">
  </div>
  <div class="w3-cell w3-container">
    <h3>Frozen</h3>
    <p>The response to the animations was ridiculous.</p>
  </div>
</div>
