A radial wipe that sweeps clockwise like a clock hand using conic-gradient with a sharp colour stop driven by interpolate(). The wipe progressively reveals Scene B underneath as the angle moves from 0 to 360 degrees.
Wipe direction (clockwise/counter-clockwise) and speed are configurable. The clock wipe is a distinctive transition that draws the eye — ideal for time-themed content, countdown reveals, or any scene change that wants more personality than a simple cut.
