SVG Mask Reveal
```
## Install
That writes one file: `compositions/components/svg-mask-reveal.html`.
## Paste it into your composition
Open `compositions/components/svg-mask-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 |
| --- | --- | --- | --- |
| `text` | `REVEAL` | string | Text used as the SVG mask window. |
| `revealProgress` | `100` | 0% to 100%, step 1% | Final revealed width of the wordmark. |
| `featherPx` | `24` | 0px to 120px, step 1px | Softness of the traveling reveal edge. |
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
```
