Notes

• The WhatsApp session is stored locally on each laptop. Users scan the QR once and stay linked until WhatsApp logs the session out.
• The login browser is bundled with the Windows build and runs headlessly. The QR is generated in the main process and displayed by the Electron renderer.
• The app loads live WhatsApp Web rather than packaging a stale WhatsApp Web HTML cache. This allows WhatsApp Web updates to be picked up without rebuilding the app.
• This app uses WhatsApp Web automation libraries, so behavior can change if WhatsApp changes the web client.
