  Avatar Group Hover - transitions.dev-inspired primitive for HyperFrames.

  Paste the markup and CSS 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 consumes. The timeline recipe below is untouched by them: it still
  drives one lift offset, and these decide what it lifts.

    - size (small | standard | large, default standard): avatar diameter,
      42px, 54px or 70px. The initials scale with it.
    - overlap (tight | standard | loose, default standard): how far each
      avatar tucks under the one before it, as a share of its own diameter:
      half, a third, or barely an eighth.
    - accent (blue | violet | green, default blue): the colour the avatar
      gradient resolves into out of the shared near-black.

  On every default the result is identical to the original: 54px avatars
  overlapping by 18px in the blue gradient.

## Install

<InstallCommand command="npx hyperframes add avatar-group-hover" item="avatar-group-hover" />

That writes one file: `compositions/components/avatar-group-hover.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 |
| --- | --- | --- | --- |
| `size` | `standard` | `small`, `standard`, `large` | Avatar diameter, with the initials scaling alongside it. |
| `overlap` | `standard` | `tight`, `standard`, `loose` | How far each avatar tucks under the one before it, as a share of its own diameter. |
| `accent` | `blue` | `blue`, `violet`, `green` | Colour the avatar gradient resolves into. |

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
<div
  data-composition-id="avatar-group-hover"
  data-composition-src="compositions/components/avatar-group-hover.html"
  data-variable-values='{"size":"standard","overlap":"standard","accent":"blue"}'
></div>
```
