문서 사이트에서 MDX 데모 밖에서도 컴포넌트 코드를 자유롭게 작성·실행하고 링크로 공유할 수 있는 /playground 를 추가한다. - 코드는 lz-string 으로 압축해 쿼리스트링에 담아 공유 URL 생성 - 배경 투명 전환/테마 전환/코드 복사 툴바 제공 - playground 는 전용 툴바를 쓰므로 GNB 는 노출하지 않음 - 기존 데모 Editor 가 높이를 상속받을 수 있도록 sx prop 추가 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

WalkthroughPlayground 페이지를 추가했습니다. 코드 편집, 미리보기, 테마 및 투명도 전환, 코드 복사, 공유 URL 생성을 지원합니다. URL 상태는 압축된 코드와 투명도 설정으로 저장됩니다. Playground 경로에서는 GNB를 숨깁니다. ChangesPlayground 기능
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔴 Critical · up to Shared playground links currently execute their code on the documentation site's origin, which could let a malicious link access same-origin browser data or make authenticated requests; this security issue should be fixed before merge.

- Around line 19-23: Update the decompression return handling in parseShareState
so a valid empty string remains '', while only a decompression result of null
indicates failure and returns null. Replace the falsy fallback behavior without
changing the existing input normalization.
In `@docs/src/features/playground/components/playground/hooks.ts`:
- Around line 50-56: Update handleCopy to stop reading the document selection
and always pass the editor value to copy, so selecting preview or error text
cannot change the copied content.
In `@docs/src/features/playground/components/playground/index.tsx`:
- Around line 29-34: Update the Playground component and useReactDemoRunner
integration so code from useInitialShareState is never executed on the
documentation site origin. Move preview execution into a separate-origin
sandboxed iframe without allow-same-origin, and define a postMessage contract
that sends only required inputs and returns the rendered output or errors; keep
react-runner execution and its returned element inside that isolated context.

빈 코드와 압축 해제 실패를 구분하세요.
유효한 빈 코드는 압축 해제 후 ''이 됩니다. 현재 decompressed || null은 이를 null로 변환하므로 parseShareState가 PLAYGROUND_DEFAULT_CODE를 복원합니다. decompressed === null ? null : decompressed로 변경하세요.

공유 URL의 코드를 문서 사이트 origin에서 실행하지 마세요.
initialState.code는 URL 쿼리에서 생성되고 즉시 useReactDemoRunner에 전달됩니다. 악성 공유 링크를 연 사용자의 브라우저에서 해당 코드가 문서 사이트와 같은 origin으로 실행됩니다. 이 코드는 접근 가능한 DOM과 브라우저 저장소를 읽고, 인증된 same-origin 요청을 만들 수 있습니다.
미리보기를 별도 origin의 sandboxed iframe으로 분리하세요. allow-same-origin을 부여하지 말고, 필요한 입력과 출력만 postMessage 계약으로 전달하세요. react-runner는 전달된 코드를 실행하고 결과 element를 반환하는 API입니다. (npmjs.com)
