Locked Nucleus Orbit
```
## Install
That writes one file: `compositions/components/locked-nucleus-orbit.html`.
## Paste it into your composition
Open `compositions/components/locked-nucleus-orbit.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` | `core` | string | Text displayed inside the fixed center nucleus. |
| `accent` | `green` | `green`, `blue`, `violet` | Color used by the nucleus, rings, and satellite markers. |
| `satellites` | `4` | 3 to 6, step 1 | Number of orbiting copy chips. |
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:
