- Create docs/customization-guide.md with guidance on replacing demo functionality
- Add customization section to main README
- Fix all references to renamed oauth-architecture-patterns.md
- Update repository structure comments to clarify what to replace vs keep
Consolidate three redundant 'Production Replacement' sections into
a single canonical location in docs/oauth-architecture-patterns.md.
Both server READMEs now point to this guide.
Simplified the repository to have a single OAuth pattern with separate auth and MCP servers at the top level. Preserved embedded OAuth documentation as an alternative pattern.
