## Install

```bash Terminal
npx hyperframes add hw-underline
```

That writes `compositions/components/hw-underline.html`, plus 1 supporting file under `assets/fonts/`.

## Paste it into your composition

Open `compositions/components/hw-underline.html` and copy what is inside into your own composition.

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

## Add it to a project

### Ask your agent

```text
Add the Squiggle Marks component from the HyperFrames Catalog to this project.
Replace the demo content with mine and match the existing design and timing.
```

### Install from the terminal

```bash
npx hyperframes add hw-underline
```

## Use it

Ask your agent to apply the component to the intended element and preserve the project’s existing timing.

**Wiring it by hand.** Open `compositions/components/hw-underline.html` and paste its contents into your composition. The comment header in that file contains any item-specific instructions.
