## JavaScript
```js
/* No JavaScript — the confirmation tag slides in via translateX as the label nudges over. */
```

How this works

Beside the box sit two layers: the main label and a small confirmation tag positioned to its left, initially translated off-position and transparent. On :checked the tag slides into place (translateX → 0, opacity → 1) while the main label nudges over with its own translateX to make visual room — all with transform, so neighbouring rows never shift.

The box gets a standard check. Because everything moves via transform/opacity, the composition stays crisp at 60fps. The native input stays sr-only and focusable with a :focus-visible ring.

Reduced-motion collapses the slide to a simple crossfade so the confirmation still appears without lateral motion.

Make it yours

  • Change the tag copy (Saved, Added, Applied…) and its colour.
  • Adjust slide distance/direction via the tag's start translateX.
  • Tune how far the main label nudges to balance the composition.
  • Recolour the box + tag via --accent.

Gotchas — read before shipping

  • Move both layers with transform, not margins, so the row height/width never changes.
  • Reserve enough horizontal space (or let the tag overlay) so the slide-in doesn't clip.
  • Keep the checkbox the real state; the sliding tag is supplementary feedback.
