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 | | - | - | - | - | | `captions` | `Instant previews,Zero config,Ship on Friday` | string | Comma-separated feature captions shown beside the pinned mock. | | `accent` | `violet` | `green`, `blue`, `violet` | Accent tint used across the mock states. | 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 theme={null}
