oci-landing-zones/oci-landing-zone-operating-entities ? reverse-engineered prompt

Build me an OCI landing zone project that gives teams a clear way to onboard and run organizations in Oracle Cloud.

I want a clean repository that lays out the main blueprint options for a single operating entity, multiple operating entities, and a multi tenancy setup, with supporting add ons for things like shared network patterns and other best practice helpers. It should also include a place for workload extensions so people can plug in common workloads later without rewriting the core setup.

Please make it feel like a real source of truth for an OCI landing zone, with good docs, a helpful getting started flow, and an FAQ for the common questions people will have when choosing the right blueprint. Keep it secure, declarative, and easy to extend, and use current OCI guidance if you need to look things up online.
