  • Organized sections: Core Types, File Storage, Security Types, Encryption Backends, Password Hashers, Mutable Types, Utilities, Constants
  • Explicit class documentation for all exported types
  • Fixes cross-reference warnings (JsonB, HashedPassword, etc.)

• ✅ Enhance Base Reference (docs/reference/base.rst)

  • Organized sections: UUID Models, BigInt Models, NanoID Models, Declarative Base
  • Explicit class documentation for all base classes
