Blazor equivalents

Blazor exposes the same surface as parameters and @ref methods:

Member	Description
MinZoom / MaxZoom / ShowZoomControls / ShowToolLabels / ShowStrokeWidthPicker / StrokeWidthPresets	Parameters, same defaults as MAUI
ZoomLevel	Read-only property holding the current factor
ZoomLevelChanged	EventCallback<double> raised for gestures and code alike
ZoomInAsync() / ZoomOutAsync() / ZoomToFitAsync() / SetZoomAsync(double)	Zoom from code
AllowRectangle / AllowEllipse / AllowCircle / ShowShapeFillPicker	Parameters, same defaults as MAUI
ShapeFillColor	A #rrggbb string rather than a Color; null or empty leaves shapes unfilled
ShapeFillOpacity	double (0-1, default 0.35) – Blazor only, because <input type="color"> cannot carry alpha; MAUI keeps it in the Color
SetModeAsync("rect" | "ellipse" | "circle")	Selects a shape tool from code
ToolbarActions	RenderFragment rendered at the trailing edge of the default toolbar
CropApplyText / CropCancelText	Crop bar labels
