Switch — thumb travel

FancyUI FANCYUI

Thumb travel and track tint are one transition, so the change reads as one event.

#minimal#select

Use in FancyUI

The thumb's travel and the track's colour run on the same timing, so on and off read as a single move rather than two changes.

Settings that apply immediately, without a save button.

A native checkbox with `role="switch"`, so Space toggles it and the state is announced. Travel is gated by reduced motion.
