 ## Implementation Order
 
 1. ✅ `GetReferencedViews()` - Foundation for view dependencies
-2. 🔲 `ReferencesOtherViews()` simplification - Use `GetReferencedViews().Any()` as default
-3. 🔲 `DependsOnSuperViewContentSize` - Reduce type checking in `DimAuto`
-4. 🔲 `CanContributeToAutoSizing` - Simplify auto-sizing logic
-5. 🔲 `GetMinimumContribution()` - Move calculation logic into types
