Build a neon iOS-style toggle.

## Structure
- Visually hidden checkbox + a 88x48 pill track + 38px circular thumb
- Wrap in a <label> so the whole track is clickable

## Animation
- Thumb travel: translateX(40px)
- Timing: 0.45s cubic-bezier(0.34, 1.56, 0.64, 1) — overshoot then

About this effect

A single accessible checkbox restyled as a neon toggle. When on, the track fills with an accent gradient and the thumb blooms with stacked box-shadows. The motion uses a springy cubic-bezier so the thumb overshoots, then settles.
