### Preserved (DynamicIsland Features):
2. ⚠️ **components/Live activities/SystemEventIndicatorModifier.swift** (166 lines):

   - **Reason**: DynamicIsland has `progressBarStyle` enum (`.gradient`, `.hierarchical`, `.segmented`)
   - **Reason**: boring.notch only has `enableGradient` boolean
   - **Decision**: Keep DynamicIsland version (MORE features)

3. ⚠️ **models/Constants.swift** (237 lines):
   - **Reason**: Removes DynamicIsland-specific enums needed for custom features
   - **Decision**: Keep DynamicIsland version
