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 Effects

🎯 한 줄 통찰 (One-line insight)

Effect classes and color classes are designed to STACK, not replace each other — combining w3-hover-opacity with any w3-hover-<color> class (e.g. w3-hover-red) produces a lighter/softer version of that hover color, meaning the effects system was built as a compositional layer on top of the existing color system rather than a standalone feature. [S1]

🧠 핵심 개념 (Core concepts)

Opacity tiers — w3-opacity-min (0.75), w3-opacity (0.6), w3-opacity-max (0.25) — three fixed transparency levels, no arbitrary values. [S1]
Grayscale tiers — w3-grayscale-min (50%), w3-grayscale (75%), w3-grayscale-max (100%) — not supported in IE 11 and earlier. [S1]
Sepia tiers — w3-sepia-min (50%), w3-sepia (75%), w3-sepia-max (100%) — also not supported in IE 11 and earlier. [S1]
Hover variants — w3-hover-opacity, w3-hover-grayscale, w3-hover-sepia — apply the effect only on mouse-over, not by default. [S1]
Stacking hover-opacity with hover-color — combining w3-hover-opacity with a w3-hover-<color> class softens/lightens that hover color. [S1]

📖 세부 내용 (Details)

Three opacity tiers on images: <img src="image.jpg" class="w3-opacity-min"><img src="image.jpg" class="w3-opacity"><img src="image.jpg" class="w3-opacity-max">. [S1]
Hover-only effects: <img src="image.jpg" class="w3-hover-opacity"><img src="image.jpg" class="w3-hover-grayscale"><img src="image.jpg" class="w3-hover-sepia">. [S1]
Combined hover color + opacity: <div class="w3-border w3-hover-opacity w3-hover-red"><p>w3-hover-red with w3-hover-opacity</p></div> — produces a lighter red on hover than w3-hover-red alone. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

IE 11 호환성 경고: w3-grayscale 계열과 w3-sepia 계열 클래스 모두 IE 11 이하 버전에서 지원되지 않는다고 원문에 명시됨 — 구형 브라우저 지원이 필요한 프로젝트에서는 주의 필요. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — hover-opacity와 hover-color를 조합해 부드러운 호버 색상을 만드는 조합 기법이 실전 UI 디테일 작업의 대표 활용 사례다. [S1]

💻 코드 패턴 (Code patterns)

Stacking hover-opacity with a hover-color class for a softened hover effect (HTML/CSS):

<div class="w3-border w3-hover-opacity w3-hover-red">
  <p>w3-hover-red with w3-hover-opacity</p>
</div>
