docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동

최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치. 콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서 전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한 업데이트0615/무제 3.canvas 뿐).

+# Styletron
+
+## 매 한 줄
+> **"매 atomic CSS-in-JS 의 pioneer"**. Uber 가 만든 styling library — 매 declared style 을 atomic class (`.a { color: red }`) 로 deduplicate, 매 SSR-friendly. 2026 perspective: 매 historical interest — 현재 의 mainstream 은 zero-runtime (vanilla-extract, Linaria, Panda CSS) 또는 utility (Tailwind v4).
+
+## 매 핵심
+
+### 매 idea
+- 매 styled component 의 declared CSS 를 atomic single-property class 로 split.
+- 매 동일 declaration 은 한 class 의 share → 매 small bundle.
+- Runtime 의 dedupe + SSR 의 style extract.
+
+### 매 Styletron 의 modern 위치
+- 매 BaseWeb (Uber UI lib) 의 default styling engine.
+- Production 사용 의 still alive 그러나 매 new project 의 default 가 아님.
+- 매 atomic 의 idea 는 Tailwind / UnoCSS 가 inherit (compile-time).
+
+### 매 modern alternatives (2026)
+- **vanilla-extract**: zero-runtime, type-safe.
+- **Panda CSS**: build-time atomic.
+- **Tailwind CSS v4**: 매 utility-first mainstream.
+- **CSS Modules + plain CSS**: 매 simplest baseline.
+
+### 매 응용
+1. BaseWeb component library 사용.
+2. Legacy Uber-stack codebase 유지보수.
+3. 매 historical case study (atomic CSS 의 origin).
+
+## 💻 패턴
+
+### Setup (React)
+```typescript
+import { Provider as StyletronProvider } from "styletron-react";
+import { Client as Styletron } from "styletron-engine-atomic";
+
+const engine = new Styletron();
+
+export function App() {
+  return (
+    <StyletronProvider value={engine}>
+      <Page />
+    </StyletronProvider>
+  );
+}
+```
+
+### styled component
+```typescript
+import { styled } from "styletron-react";
+
+const Button = styled("button", {
+  backgroundColor: "blue",
+  color: "white",
+  padding: "8px 16px",
+  borderRadius: "4px",
+});
+
+// usage: <Button>Click</Button>
+```
+
+### Dynamic prop-based styling
+```typescript
+const Button = styled<"button", { $primary?: boolean }>("button", ({ $primary }) => ({
+  backgroundColor: $primary ? "blue" : "gray",
+  color: "white",
+}));
+```
+
+### useStyletron hook
+```typescript
+import { useStyletron } from "styletron-react";
+
+function Card() {
+  const [css] = useStyletron();
+  return <div className={css({ padding: "16px", boxShadow: "0 2px 4px rgba(0,0,0,0.1)" })}>Hello</div>;
+}
+```
+
+### SSR (Next.js)
+```typescript
+// pages/_document.tsx
+import Document, { Html, Head, Main, NextScript } from "next/document";
+import { Server, Sheet } from "styletron-engine-atomic";
+import { Provider } from "styletron-react";
+
+export default class MyDoc extends Document {
+  static async getInitialProps(ctx) {
+    const engine = new Server();
+    const initialProps = await Document.getInitialProps({
+      ...ctx,
+      renderPage: () => ctx.renderPage({
+        enhanceApp: (App) => (props) => (
+          <Provider value={engine}><App {...props} /></Provider>
+        ),
+      }),
+    });
+    return { ...initialProps, stylesheets: engine.getStylesheets() };
+  }
+  render() {
+    return (
+      <Html>
+        <Head>
+          {this.props.stylesheets.map((s, i) => (
+            <style className="_styletron_hydrate_" dangerouslySetInnerHTML={{ __html: s.css }} key={i} />
+          ))}
+        </Head>
+        <body><Main /><NextScript /></body>
+      </Html>
+    );
+  }
+}
+```
+
+### Migration to vanilla-extract (modern)
+```typescript
+// styles.css.ts
+import { style } from "@vanilla-extract/css";
+export const button = style({
+  backgroundColor: "blue",
+  color: "white",
+  padding: "8px 16px",
+});
+// Component.tsx
+import { button } from "./styles.css";
+<button className={button}>Click</button>
+```
+
+## 매 결정 기준
+| 상황 | Approach |
+|---|---|
+| 매 BaseWeb 사용 codebase | Styletron (forced) |
+| 매 new project (2026) | Tailwind v4 또는 vanilla-extract |
+| 매 type-safe + zero-runtime | vanilla-extract |
+| 매 quick prototype | Tailwind |
+| 매 library 배포 (no runtime) | Linaria / Panda CSS |
+
+**기본값**: 매 new code 는 Tailwind v4 또는 vanilla-extract. 매 Styletron 신규 채택 의 X.
+
+## 🔗 Graph
+- 부모: [[CSS_Architecture_and_Styling|CSS-in-JS]]
+- 변형: [[vanilla-extract]] · [[Panda-CSS]]
+- 응용: [[BaseWeb]] · [[React]]
+- Adjacent: [[Tailwind CSS]] · [[Atomic-CSS]]
+
+## 🤖 LLM 활용
+**언제**: BaseWeb codebase 의 maintenance, 매 atomic CSS history 의 understand.
+**언제 X**: 매 greenfield project — modern alternatives 가 superior (zero-runtime, type-safe).
+
+## ❌ 안티패턴
+- **매 new project 의 Styletron 채택**: 매 ecosystem momentum 이 vanilla-extract / Tailwind 로 이동 — 매 future-proof X.
+- **Runtime dedupe overhead**: 매 large app 에서 visible — 매 build-time atomic (Panda) 이 우월.
+- **Styletron + Tailwind 동시**: 매 conflicting paradigm — pick one.
+
+## 🧪 검증 / 중복
+- Verified (styletron.org, GitHub uber/styletron, Uber engineering blog 2017).
+- 신뢰도 A (매 historically), 매 modern adoption 의 declining.
