3D Neumorphic Pill Toggle

A tactile soft-UI switch for modern immersive dashboards: the track is carved INTO the surface with inset shadows while the knob extrudes OUT of it — and pressing gives a physical push-down before the knob glides across and an accent ring wakes up.

## JavaScript
```js
/* No JavaScript — dual-source inset shadows deboss the track, outset shadows emboss the knob, and :active collapses them for a physical push-down. */
```

How this works

Neumorphism is dual-source lighting: every element carries two box-shadow layers — a dark shadow toward the bottom-right and a light one toward the top-left. The track uses inset versions of both, reading as debossed; the knob uses outset versions, reading as embossed on the same surface.

:active scales the knob down and collapses its shadows, simulating the press; release lets the transform glide it across the pit. When checked, an inner accent glow tints the cavity so state is readable beyond knob position alone.

Make it yours

  • The whole illusion keys off --surface, --shade and --light — shift all three together to retheme.
  • Deepen the carve by raising the inset blur/offset values.
  • Change the checked accent via --accent.
  • Round less (border-radius 14px) for a squircle variant.

Gotchas — read before shipping

  • Neumorphism only works when track, knob and page share the SAME base surface color — contrast breaks the molded-from-one-material illusion.
  • Soft shadows are low-contrast by nature: keep the accent state and focus ring strong for accessibility.
  • Animate the press with transform:scale(), never by shrinking width/height.
