jameskk-syy/FrappeSaas ? reverse-engineered prompt

Build me a simple Frappe app called Frappesaas that can be installed inside a Frappe site and feels like a basic SaaS starter.

I want it to look clean and be ready for a real project, with the usual app structure, a homepage or dashboard style screen, and a few example modules or doctypes that show how the app is meant to work. Keep it lightweight and easy to extend, since this is just the starting point for a Frappe based product.

If anything in the latest Frappe docs would help, look it up online and follow current best practice. Make sure the app installs without errors, uses the project name consistently, and includes enough placeholder content so I can build on it later.
