A sunburst that fans out behind a hero as p goes 0 to 1 (kind burst, --s turns it), or horizontal speed streaks that sweep across the frame (kind speed, --s slides them). Plain CSS gradients, no script; standalone it renders finished.

| Field | Type | Required |
|---|---|---|
| kind | "burst" | "speed" (optional, default "burst") | optional |
| angle | integer. Kind speed only: the direction the lines run, in degrees clockwise from horizontal, -180 to 180. Default 0 (horizontal lines streaming left to right as step advances). The lines and their travel turn together inside the same 16:9 frame, clipped to it. Ignored by burst; 0 or a non-number keeps the horizontal look exactly. | optional |
| count | integer. Rays or lines, 4-64. Default 24. | optional |
| thickness | number. Share of each step that is ray, 0.1-0.9. Default 0.5. | optional |
| spin | integer. Degrees turned at --s = 1 (burst), -360 to 360. Default 45. | optional |
| strength | number. Peak opacity, 0.05-1. Default 0.35. | optional |
| accent | "#rrggbb". Default the stage accent. | optional |
