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.

CSS RWD Intro

🎯 한 줄 통찰 (One-line insight)

Responsive web design is about creating web pages that look good on all devices, using HTML and CSS to automatically resize, hide, shrink, or enlarge a website so it adapts to desktops, tablets, and mobile phones. [S1]

🧠 핵심 개념 (Core concepts)

Responsive web design — about creating web pages that look good on all devices. [S1]
HTML + CSS — RWD uses HTML and CSS to automatically resize, hide, shrink, or enlarge a website, to make it look good on all devices. [S1]
Device coverage — targets desktops, tablets, and mobile phones. [S1]
Essential elements — the viewport <meta> tag, flexible layout (grid and flex), and media queries. [S1]

🧩 추출된 패턴 (Extracted patterns)

Adapt, do not duplicate — one set of HTML/CSS resizes and rearranges itself per device, rather than maintaining separate sites. [S1]
Three-pillar foundation — the viewport meta tag, a flexible layout (grid/flex), and media queries together enable responsiveness. [S1]

📖 세부 내용 (Details)

Responsive web design is about creating web pages that look good on all devices. Responsive design involves using HTML and CSS to automatically resize, hide, shrink, or enlarge a website, to make it look good on all devices. [S1]

The page identifies three essential RWD elements: the viewport <meta> tag, a flexible layout (grid and flex), and media queries. It also references three device categories — desktops, tablets, and mobile phones — with accompanying device illustrations. [S1]
