Interface CanvasFocusReturn

Live boolean — true when the element has DOM focus. Triggers re-renders when the focus state changes (set via React state).

Spread onto the focusable element (e.g. the canvas). Includes tabIndex, onFocus, onBlur.

Stable getter for the live focused state. Use inside per-frame closures like RenderLayer.draw, where the layer is constructed once and reading focused directly would capture the value at construction time. The getter always returns the current value.

Imperative focus / blur. Useful for tests and programmatic control.
