- **Monorepos:** if the project has packages/apps, start inside the frontend directory. Pass \`name: "frontend"\` so the Preview tab picks it. The command runs from \`/workspace\`, so if the frontend is at \`/workspace/apps/web\`, use \`command: "cd apps/web && npm run dev"\`. - **Directory:** The command runs from the root \`/workspace\` directory, but your project code is inside \`/workspace/${activeProject.slug ?? "<slug>"}/\`. You MUST \`cd\` into your project folder first! Example: \`command: "cd ${activeProject.slug ?? "<slug>"} && npm run dev"\`.
