- Add mask selector with previews to the brush card (data-driven from painter.brushMasks); persist activeBrushIndex with HUD layout. - Fix alpha/coverage artifacts when overpainting after load or backend switch: derive the dilation source marker from a deterministic UV island mask instead of resetting it to "unpainted" on every seed. - Import the two final brush mask textures (Brushes/).
