readonlyname(string): – The dtype name
readonlycomponents(number): – Number of components (1 for scalars, 2 for complex, 4 for quaternion, etc.)
readonlycomponentType(DType): – The underlying storage dtype for each component
readonlylayout('interleaved' | 'planar'): – Memory layout for multi-component types
readonlyisBuiltin(boolean): – Whether this is a built-in dtype
readonlycomponentNames(readonly string[])optional: – Component names if defined (e.g., ['w', 'x', 'y', 'z'] for quaternions)
readonlyallowComponentView(boolean)optional: – Whether .view() can expose underlying components
