## Install
That writes one file: `compositions/components/ascii-trail-reveal.html`.
## Paste it into your composition
Open `compositions/components/ascii-trail-reveal.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.
## 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 |
| --- | --- | --- | --- |
| `label` | `The reveal` | string | Text shown on the revealed panel. |
| `accent` | `green` | `green`, `blue`, `violet` | Color used by the trail and revealed panel. |
| `trail_width` | `narrow` | `narrow`, `wide` | Width of the cell reveal tail around the authored path. |
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
```
