/* Weather in a teacup — the teacup on the Slopwright's shelf, between commissions, with a small storm over the rim.
   The cup and saucer are gradients and border-radius; the cloud drifts on a transform; the rain is a repeating
   gradient on a tall layer that slides down inside a clipped box; a small bolt flashes by opacity now and then (two
   flicks every seven seconds, never more than three a second); steam curls up from the rim. A registered angle turns
   the cloud's inner swirl. Reduced motion clears the weather: a still cup on a still shelf.
   Designed by machine for the Slopwright. */
