### Node.js Version Requirements

This project has different Node.js requirements depending on the use
case:

#### Building the Electron App (Root package.json)
- **Required:** Node.js >= 24
- **Why:** Build tools like @electron/notarize and semantic-release
require Node.js 24+
- **Affected files:** `/package.json`

#### Running the Backend/Server (Backend package.json)
- **Required:** Node.js >= 20
- **Why:** The MQTT server runtime is compatible with Node.js 20+
- **Affected files:** `/backend/package.json`

#### Frontend App (App package.json)  
- **Required:** Node.js >= 20
- **Why:** React and webpack tools are compatible with Node.js 20+
- **Affected files:** `/app/package.json`
