Antigravity Agent c24165b8bc refactor(topics): 멀티 에이전트용 지식 재편 — _Common(공통 기본기) + Domain_* 구조

에이전트 8종(대화형/프로그래머 C·S/디자이너/설계자/기획자/QA/PD/PM)에게
[공통 기본 능력 + 롤별 Specialty] 2층으로 지식을 주입하기 위한 재분류.
문서 내용·포맷은 무수정, 폴더 이동만 (6,372개 문서 수 보존 확인).

- Topic_Programming → Domain_Programming (내부 구조 보존)
- Topic_Graphic → Domain_Design
- Topic_Business → Domain_Product
- Topic_General → Domain_General
- _Common 신설: Math(구 Topic_Math_Specialty), Reasoning(구 General/From_Thinking & Reasoning),
  Reasoning_Creativity(구 General/From_창의성), Communication(Poetic_Blog_Writing + From_writing)
- 타 도메인의 From_* 폴더는 유지 (출처 표기일 뿐, 이미 도메인에 맞게 분류된 문서)
- 빈 폴더 정리 (memory/procedures)
- 에이전트→폴더 매핑은 workspace의 .astra/agent-knowledge-map.json (9개 에이전트)

W3CSS Images

🎯 한 줄 통찰 (One-line insight)

w3-image scales DOWN but never scales UP beyond the image's original size — a deliberate one-directional responsiveness distinct from style="width:100%" (which scales both up and down), meaning w3-image is the right choice specifically when you want a photo to shrink gracefully on small screens without ever appearing artificially blown-up/pixelated on large ones. [S1]

🧠 핵심 개념 (Core concepts)

w3-round / w3-circle / w3-border — reused shape/border classes apply directly to <img>. [S1]
w3-image — responsive: scales DOWN to fit container, never scales UP past original size. [S1]
style="width:100%" — scales both up AND down (fully fluid), unlike w3-image. [S1]
w3-opacity / w3-opacity-min / w3-opacity-max — three opacity intensity tiers. [S1]
w3-grayscale / w3-sepia (with -min/-max variants) — visual filter effects; NOT supported in IE11 and earlier. [S1]
w3-hover-opacity / w3-hover-grayscale / w3-hover-sepia — effects applied only on hover. [S1]
w3-hover-opacity-off — the inverse: an already-transparent image (w3-opacity) becomes FULLY opaque on hover, rather than the more common "transparent on hover" pattern. [S1]
Photo album via Responsive Grid — w3-third + w3-card + <img style="width:100%"> + w3-container caption, repeated for a gallery layout. [S1]

📖 세부 내용 (Details)

Never-scale-up responsive image: <img src="img_lights.jpg" alt="Lights" class="w3-image">. [S1]
Fully fluid (scales both ways): <img src="img_lights.jpg" alt="Lights" style="width:100%">. [S1]
Grayscale (not IE11-safe): <img src="image.jpg" class="w3-grayscale">. [S1]
Inverse hover effect: <img src="snowtops.jpg" class="w3-opacity w3-hover-opacity-off" alt="Alps"> — starts transparent, becomes fully opaque on hover. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

grayscale/sepia의 브라우저 제약: w3-grayscale과 w3-sepia 클래스 모두 IE11 이하에서 지원되지 않는다는 점이 각각 명시적으로 경고됨. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — Responsive Grid(w3-third)로 구성한 사진 앨범이 반응형 이미지 갤러리의 대표 실전 사례다. [S1]

💻 코드 패턴 (Code patterns)

Image that fades in on hover, from transparent to fully opaque (HTML):

<img src="snowtops.jpg" class="w3-opacity w3-hover-opacity-off" alt="Alps">
