## Install

<InstallCommand command="npx hyperframes add icon-swap" />

That writes one file: `compositions/components/icon-swap.html`.

## Variables

Every one of these has a default, so the piece works untouched. Set the ones you
want to change on the element:

| Variable | Default    | Accepts                       | What it does                                                                                    |
| -------- | ---------- | ----------------------------- | ----------------------------------------------------------------------------------------------- |
| `tone`   | `dark`     | `dark`, `light`, `accent`     | Button fill and glyph colour. Accent rides --brand.                                             |
| `size`   | `standard` | `small`, `standard`, `large`  | Button box and glyph size, from a toolbar chip to a hero action.                                |
| `shape`  | `rounded`  | `rounded`, `circle`, `square` | Corner treatment of the button box.                                                             |
| `blur`   | `standard` | `soft`, `standard`, `heavy`   | Scales the blur radius the timeline drives through the swap, from a light haze to a full smear. |

Set them with `data-variable-values` on the element that mounts it. These are the
defaults, so this behaves exactly like the preview above until you change one:

```html wrap theme={null}
<div
  data-composition-id="icon-swap"
  data-composition-src="compositions/components/icon-swap.html"
  data-variable-values='{"tone":"dark","size":"standard","shape":"rounded","blur":"standard"}'
></div>
```

## Source

<Accordion title={`icon-swap.html`}>
  ```html theme={null}
  <!--
    Icon Swap - transitions.dev-inspired primitive for HyperFrames.

    Paste the markup, CSS and script into a composition. Use the timeline integration
    note at the bottom as the starting point for deterministic GSAP animation.

    Variables. The script reads each one, falls back to the declared default on anything
    missing or unrecognised, and writes the result as a custom property the CSS above
    consumes. The timeline recipe below is untouched by them.

      - tone (dark | light | accent, default dark): button fill and glyph colour. dark is the
        matte chip, light inverts it for bright frames, accent rides --brand.
      - size (small | standard | large, default standard): the button box and the glyph inside
        it, 44px, 58px or 76px.
      - shape (rounded | circle | square, default rounded): corner radius of the box.
      - blur (soft | standard | heavy, default standard): scales the blur radius the timeline
        drives through the swap, from a light haze to a full smear.

    On every default the result is identical to the original: a 58px near-black chip with
    16px corners and an 8px swap blur.
