Antigravity Agent 9148c358d0 docs(10_Wiki): 위키 전체 재구성 — Topic_* 폴더를 4개 카테고리로 통합 + 대규모 중복 제거
Topic_Agent/Topic_Blog/Topics/Topics_Biz/Topics_Meeting/Topics_Rag의 마크다운 지식 문서를
Topic_General/Topic_Programming/Topic_Graphic/Topic_Business 4개 카테고리로 재분류.

- 중복 제거: frontmatter의 status:duplicate/merged + duplicate_of/redirect_to 필드로
  자기 자신을 중복으로 선언한 리다이렉트 stub 1032개 제거, 완전 동일 내용 파일 472개 제거,
  동일 파일명·다른 내용 충돌 시 더 큰(완전한) 버전만 유지(162개 제거) — 총 1639개 중복 제거.
- 분류: 폴더 단위로 명확한 항목(AI_and_ML/Coding/Architecture 등 → Programming,
  Comfyui/Visual_Effects → Graphic, Topics_Biz/Topics_Meeting/사업 등 → Business,
  Poetic_Blog_Writing/창의성/Game_Design 등 → General)은 폴더 우선순위로,
  나머지 혼재 폴더(Topic_Agent/Topic_Blog/Topics 루트/Thinking & Reasoning/Other/UI_UX_Assets)는
  title/tags 키워드 스코어링으로 파일 단위 분류(불명확한 경우 General로 폴백).
  원본 폴더명은 "From_*" 서브폴더로 보존해 추적 가능성 유지.
- 최종 배치: Programming 2784 / General 1608 / Graphic 285 / Business 249 = 4926개 문서.
- 에이전트 운영 상태(.astra/.agent/.obsidian/sessions/memory/_company/docs/lessons/_shared/src)는
  지식 콘텐츠가 아니므로 재분류 대상에서 제외하고 원위치 유지.
- Topics/Topic_email(상위 보호 폴더 Topic_email과 파일명 100% 중복) 삭제 — 보호 폴더 자체는 미변경.
- 완전히 비게 된 Topic_Agent/Topic_Blog/Topics_Biz/Topics_Rag 폴더 제거.

Accordion

매 한 줄

"매 expand-on-demand UI primitive". 매 1980s desktop GUI 의 origin → 매 2026 web 의 ARIA disclosure pattern, FAQ/sidebar/settings 의 default density-saving widget.

매 핵심

매 mechanism

  • 매 header (button) + 매 panel (region) 의 pair.
  • aria-expanded + aria-controls + region role 의 a11y triplet.
  • 매 single-expand (radio-like) vs multi-expand (checkbox-like).

매 modern stack

  • 매 Radix UI Accordion (headless, WAI-ARIA-compliant).
  • 매 React Aria, Headless UI, shadcn/ui Accordion.
  • 매 native <details>/<summary> (free a11y, limited animation).

매 응용

  1. FAQ pages (Stripe, GitHub docs).
  2. Settings panels (VSCode sidebar).
  3. Mobile navigation drawers.

💻 패턴

Radix UI Accordion (single-expand)

import * as Accordion from '@radix-ui/react-accordion';

export function FAQ() {
  return (
    <Accordion.Root type="single" collapsible defaultValue="item-1">
      <Accordion.Item value="item-1">
        <Accordion.Trigger className="flex w-full justify-between p-4">
          What is React?
          <ChevronDown className="transition-transform data-[state=open]:rotate-180" />
        </Accordion.Trigger>
        <Accordion.Content className="overflow-hidden data-[state=open]:animate-slideDown">
          A library for UIs.
        </Accordion.Content>
      </Accordion.Item>
    </Accordion.Root>
  );
}

Native <details> (zero-JS)

<details>
  <summary>Click to expand</summary>
  <p>Hidden content.</p>
</details>

<style>
  details[open] summary ~ * { animation: slideDown 200ms ease-out; }
  @keyframes slideDown { from { opacity: 0; transform: translateY(-8px); } }
</style>

Custom hook (multi-expand)

function useAccordion(initial: string[] = []) {
  const [open, setOpen] = useState(new Set(initial));
  const toggle = (id: string) =>
    setOpen(prev => {
      const next = new Set(prev);
      next.has(id) ? next.delete(id) : next.add(id);
      return next;
    });
  return { isOpen: (id: string) => open.has(id), toggle };
}

매 height animation (interpolate to auto)

[data-state='closed'] { grid-template-rows: 0fr; }
[data-state='open']   { grid-template-rows: 1fr; }
.panel { display: grid; transition: grid-template-rows 200ms; }
.panel > div { overflow: hidden; }

매 keyboard support (Radix-equivalent)

function onKeyDown(e: KeyboardEvent) {
  if (e.key === 'ArrowDown') focusNextHeader();
  if (e.key === 'ArrowUp')   focusPrevHeader();
  if (e.key === 'Home')      focusFirstHeader();
  if (e.key === 'End')       focusLastHeader();
}

매 결정 기준

상황 Approach
0-JS, simple FAQ <details>
Animated, controlled Radix UI
Form section Custom (preserve mounted state)

기본값: Radix UI Accordion + Tailwind animations.

🔗 Graph

🤖 LLM 활용

언제: density-saving long-form lists, optional sections. 언제 X: critical information (hidden by default = missed); sequential workflows (use Stepper).

안티패턴

  • Multi-open by default 의 visual chaos: Use single-expand for nav.
  • No aria-expanded: screen readers 매 broken.
  • Animating height: auto: Use grid-rows trick or max-height.

🧪 검증 / 중복

  • Verified (Radix UI docs, WAI-ARIA Accordion Pattern).
  • 신뢰도 A.
