  Blur In - Operator Black content-focus reveal primitive.

  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 below consumes. The timeline recipe at the bottom is untouched by
  them: it keeps resolving the same words out of the same blur.

    - size (24 to 120, default 52, in px): the type size of the words. The gap
      between words is set in em, so it scales with this.
    - tone (strong | muted | accent, default strong): word colour. strong is
      the headline text token, muted the supporting one, accent the theme
      green, so all three track light and dark frames.
    - align (left | center | right, default left): where the words sit across
      the frame.

  On every default the result is identical to the original: 52px strong words,
  left aligned.

## Install

<InstallCommand command="npx hyperframes add blur-in" item="blur-in" />

That writes one file: `compositions/components/blur-in.html`.

## Paste it into your composition

Open `compositions/components/blur-in.html` and copy what is inside into your own composition.
The file opens with a comment header that walks you through it.

A component has no size or duration of its own. It takes both from the composition
you paste it into.

## 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` | `52` | 24px to 120px, step 2px | Type size of the revealed words in pixels; the gap between words scales with it. |
| `tone` | `strong` | `strong`, `muted`, `accent` | Word colour: strong for headlines, muted for supporting lines, accent for the brand green. |
| `align` | `left` | `left`, `center`, `right` | Horizontal alignment of the words in the frame. |

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="blur-in"
  data-composition-src="compositions/components/blur-in.html"
  data-variable-values='{"size":52,"tone":"strong","align":"left"}'
></div>
```
