Field	Type	Default	Meaning
strength	float	2.5 (fades to 0)	Max swirl angle in radians; sign = direction
radius	float	0.5	Funnel radius as a screen fraction
center_x, center_y	float	0.5, 0.5	Funnel centre in UV

Example

{
    "type": "vortex",
    "duration": 60,
    "params": { "strength": 2.5, "radius": 0.5, "center_x": 0.5, "center_y": 0.5 }
}
