/**
 * BlurVibeViewManager
 *
 * Plain SimpleViewManager + @ReactProp — works correctly under BOTH Old
 * Architecture (Paper) and New Architecture (Fabric) on Android.
 *
 * Fabric on Android calls ViewManager.updateProperties() which dispatches
 * to @ReactProp-annotated setter methods via reflection — the SAME
 * mechanism Old Architecture uses. There is no functional requirement to
 * implement the codegen interface/delegate pattern for a ViewManager to
 * work correctly under Fabric; it's an optional type-safety layer.
 *
 * Type param is ViewGroup — lowest common supertype of:
 *   BlurVibeViewApi31 (extends ReactViewGroup extends ViewGroup)
 *   BlurVibeView      (extends ReactViewGroup extends ViewGroup)
 *
 * Naming rules (prevent supertype method hiding):
 *   setBlurBorderRadius → not setBorderRadius (BaseViewManager has it)
 *   setBlurRadiusProp   → not setBlurRadius   (safety)
 *   setBlurTypeProp     → not setBlurType      (safety)
 *   setOverlayColorProp → not setOverlayColor  (safety)
