```ts
export interface AnimOnce {
  /** The state entered at the end. Absent: back to the state that was playing before. */
  then?: string
  /** Seconds before the last frame the hand-over starts, and how long it blends. Default 0.2. */
  blendOut?: number
  /** The states that may cut it short. Absent: any; `[]`: none. */
  interrupt?: string[]
  /** The bus event raised when it ends. Default `animation-end`. */
  event?: string
}
```
