Reveals content through an expanding circular clip-path that grows from the centre outward using interpolate() on the circle radius. Creates an iris/spotlight effect commonly used in film for dramatic reveals, scene openings, or focusing attention on a key element.

Reveal speed, final radius, and centre point are configurable. A subtle radial glow at the expanding edge adds polish. The clip-path approach means any content placed inside — text, images, charts — gets the reveal treatment automatically.
