Outline Minimal currentColor Toggle

A stroke-only switch drawn entirely in currentColor: hollow track, hollow thumb that fills solid when on. Because it inherits its color from surrounding text, the SAME markup works on light cards, dark cards and brand-colored banners with zero per-theme CSS.

## JavaScript
```js
/* No JavaScript — every stroke and fill is currentColor, so the identical switch inherits each container's text color; checked fills the hollow thumb solid. */
```

How this works

Every visible part uses currentColor: the track is a 2px border with transparent fill; the thumb a 2px-bordered circle that gains background:currentColor when checked. No hex codes appear in the switch rules at all — drop it into any container and it matches that container's text color, including hover and dark-mode recolors, for free.

State is double-encoded despite the minimalism: thumb position AND fill density (hollow = off, solid = on), so it survives grayscale and low vision. The demo shows one identical switch inside three differently-themed chips to prove the inheritance.

Make it yours

  • Thicken to 3px strokes for display contexts.
  • Let the on-state tint: add color:var(--accent) on :checked to shift only when on.
  • Square variant: radius 6px on track and thumb.
  • Animate the fill with a scale-up ::after instead of background for a pop-in.

Gotchas — read before shipping

  • currentColor resolves at the element — if the switch sits in muted 50%-gray text, the control is 50% gray too; wrap it or reset color where contrast would fail.
  • Keep the hollow/solid distinction — position-only state in a monochrome control fails color-independence.
  • Border+transparent backgrounds hit sub-pixel rounding at odd zoom levels; even stroke widths (2px) render cleanest.
