fajrjas/IDJAS_MSP ? reverse-engineered prompt

Build me a realistic medium sized enterprise network lab that I can open and test in Packet Tracer.

I want a clean setup that feels like a real company network, with separate areas for different teams, basic routing between them, and the usual services a business would need so the lab actually works end to end. Please make it easy to understand, organized, and ready to review from the configuration files. If you need to check current Packet Tracer best practices or command syntax, look them up online.

Also include whatever screenshots or documentation make it easy to see how the network is laid out and how the pieces connect. I want the final result to be something I can use for learning and demonstration, not just a pile of devices with no clear purpose.
