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)

HTML Headings

🎯 한 줄 통찰 (One-line insight)

HTML headings <h1><h6> express the importance and structure of content (not merely its size), with <h1> most important and <h6> least. [S1]

🧠 핵심 개념 (Core concepts)

  • Six heading levels<h1> through <h6>. [S1]
  • Importance, not size<h1> defines the most important heading; <h6> the least important. [S1]
  • Browsers add margins — browsers automatically add some white space (a margin) before and after a heading. [S1]
  • Headings are for structure — search engines use headings to index the structure and content of web pages; users skim them to grasp a page. [S1]
  • Size is styled with CSS — use the style attribute with font-size to change a heading's rendered size. [S1]

🧩 추출된 패턴 (Extracted patterns)

  • One <h1> per page — use <h1> for the main title (or logo). [S1]
  • Logical hierarchy<h1> for page title → <h2> for section titles → <h3> for subsections, in order. [S1]
  • Don't misuse headings for visuals — do not use headings just to make text big or bold; use CSS for that. [S1]
  • Resize via inline style<h1 style="font-size:60px;">…</h1>. [S1]

📖 세부 내용 (Details)

HTML Headings HTML headings are titles or subtitles that you want to display on a webpage. They are defined with the <h1> to <h6> tags. <h1> defines the most important heading; <h6> defines the least important heading: [S1]

<h1>Heading 1</h1>
<h2>Heading 2</h2>
<h3>Heading 3</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6</h6>

Note: Browsers automatically add some white space (a margin) before and after a heading. [S1]

Headings Are Important Headings are important. Search engines use the headings to index the structure and content of your web pages. Users often skim a page by its headings; it is important to use headings to show the document structure. <h1> headings should be used for main headings, followed by <h2> headings, then the less important <h3>, and so on. [S1]

Note: Use HTML headings for headings only. Don't use headings to make text BIG or bold. [S1]

Bigger Headings Each HTML heading has a default size. However, you can specify the size for any heading with the style attribute, using the CSS font-size property: [S1]

<h1 style="font-size:60px;">Heading 1</h1>

Heading reference table

Tag Description
<html> Defines the root of an HTML document
<body> Defines the document's body
<h1> to <h6> Defines HTML headings

🛠️ 적용 사례 (Applied in summary)

A typical applied structure (e.g. a travel guide) uses <h1> for the page title, <h2> for region/section titles, and <h3> for country/subsection titles — demonstrating heading hierarchy as document outline. No external project/commit applications found in the source.

💻 코드 패턴 (Code patterns)

All six heading levels (HTML):

<h1>Heading 1</h1>
<h2>Heading 2</h2>
<h3>Heading 3</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6</h6>

Resizing a heading with inline CSS:

<h1 style="font-size:60px;">Heading 1</h1>

⚖️ 모순 및 업데이트 (Contradictions & updates)

The source stresses semantics over appearance: headings should encode document structure for search engines and users, not be repurposed to make text big or bold — use CSS font-size instead. [S1]
