registry-pattern
Domain: Pure Python Packages
🎯 Motivation
A central dictionary where plugins register themselves. The host looks up registered items by key to use them.
📋 Concrete Example
A global REGISTRY = {} where plugins call REGISTRY['myfeature'] = MyClass to make features available.
🔗 Analogy
The registry pattern is a sign-up sheet — plugins write their name, and the host reads the list to call them.
