Quiet, expensive-feeling; the scene itself never moves. Callers fill the named scene slot; a token hero-and-cards default renders when it is left empty. # Light Sweep Pass A traveling key light re-shades a slotted scene: a soft diagonal gradient band crosses the frame once while every per-element highlight and shadow shifts in lockstep (all driven by one --light-x property), then the light settles into a resting key.

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 | | - | - | - | - | | `angle` | `115` | 60deg to 160deg, step 1deg | Band and highlight gradient angle in degrees. | | `sweep_at` | `0.9` | 0s to 8s, step 0.05s | Seconds after mount start when the band starts crossing. | | `strength` | `standard` | `subtle`, `standard` | Band opacity and highlight bloom multiplier. | | `accent` | `green` | `green`, `blue`, `violet` | Tint inside the band and the highlight blooms. | | `exit` | `none` | `none`, `fade`, `up` | Outgoing transition. None holds the settled key. | 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}
