Dev environment tips

• Use npm install in the project root to install all dependencies.
• Check the name field in each package's package.json to confirm the correct name—ignore the top-level one.
• Use npm run dev to start the local development server.
• Use npm run build to create a production build.
• Use npm run lint to check code quality and TypeScript types.
• Use npm run typecheck to run TypeScript type checking independently (if configured).
