EnvSync-Cloud/envsync ? reverse-engineered prompt

Build me an EnvSync style app for managing environment variables and secrets across teams.

I want a simple platform where people can log in, create apps and environments like development, staging, and production, then store, update, and pull secret values safely from the command line and from a web dashboard. It should let me see change history, roll back to a previous version, and require approval before production updates go live. Please include team access, basic roles and permissions, and an audit trail for every change.

Make the experience feel polished enough for a real product, with a landing page, dashboard, API, and CLI workflow. If you need to look up current docs for any libraries or integration details, go ahead and do that. I also want it set up so it can run locally with Docker and be ready for self hosting later.
