trailheadapps/az-insurance ? reverse-engineered prompt

Build me a sample Salesforce site for a fictional insurance company called AZ Insurance that shows how customer, partner, and marketing experiences can work in Experience Cloud and Lightning Web Runtime.

I want a polished public facing experience with a clear insurance brand, a marketing home page, and a few example sections that feel like a real customer portal and partner portal. It should be set up so the site can pull in content from Salesforce CMS, with sample text and media already ready to import, and it should feel like a real demo people can click through in a scratch org.

Please keep it close to the style of a Salesforce sample app, use modern Lightning web components, and make sure the experience site can be deployed and published cleanly. If you need to check current Salesforce docs or best practices while building it, go ahead and look them up online.
