React Review Report

React Review couldn't analyze this pull request because it couldn't find a package.json at the repository root.

This usually happens when the React app lives in a subdirectory, such as in a monorepo. For now, React Review expects the project it reviews to be at the repository root.

New issues:
- apps/website/app/copy-prompt/copy-prompt-client.tsx:52 [warning] js-batch-dom-css: Multiple sequential element.style assignments — batch with cssText or classList for fewer reflows
  Help: Batch DOM/CSS reads and writes — interleaving them inside a loop causes layout thrashing. Read first, then write
- apps/website/app/copy-prompt/copy-prompt-client.tsx:86 [warning] no-cascading-set-state: 5 setState calls in a single useEffect — consider using useReducer or deriving state
  Help: Combine into useReducer: `const [state, dispatch] = useReducer(reducer, initialState)`
