+* BarBackground - ShapePath component for rendering the bar background
+*
+* Unified shadow system. This component is a ShapePath that will be
+* a child of the unified AllBackgrounds Shape container.
+*
+* Uses 4-state per-corner system for flexible corner rendering:
+* - State -1: No radius (flat/square corner)
+* - State 0: Normal (inner curve)
+* - State 1: Horizontal inversion (outer curve on X-axis)
+* - State 2: Vertical inversion (outer curve on Y-axis)
