solari-sdk/solari-cookbook ? reverse-engineered prompt

Build me a small cookbook repo for Solari that has simple, runnable examples for each of the main things it can do.

I want one tiny example for launching a cloud browser, opening a page, and reading the content, one for using a browser with a saved profile or session, one for running code in a sandbox and reading and writing files, one for exposing a port from a sandbox so I can open it in a browser, and one for controlling a desktop by taking screenshots, clicking, and typing. Keep each example self contained and easy to run in under a minute, with both TypeScript and Python where that makes sense.

Please make the setup instructions very clear, show how to use one API key for everything, and include the little gotchas that people usually miss, like closing browser sessions properly or ending a sandbox the right way. If you need to check current Solari docs online, do that too.
