v0.2.1

Patch Changes

• #3 1b21d12 Thanks @MikeNotThePope! - Fix the Spinner so its motion is visible in light mode. The arc (top border)
  previously used a dark plum on a prominent medium-gray track, so it blended in
  and the ring looked static. A dedicated, per-mode --spinner-track token now
  gives light mode a subtle light-gray track for the arc to stand out against;
  dark mode is unchanged.
