Cursors

The unified cursor manager supports the cursor types used by the chart experience.

Some types only update the CSS cursor, while others also draw on the canvas through CursorRenderer.

Cursor type	Used for
arrow	Plain default arrow with any canvas overlay cleared.
crosshair	Precision selection and coordinate reading.
demonstration	Canvas demo highlight plus the normal crosshair cursor.
magic	Animated cursor for enhanced interaction feedback.
eraser	Theme-aware eraser cursor with a matching canvas overlay.

These cursor types are rendered through UnifiedCursorManager and CursorRenderer, not through CursorType alone.
