Function prefetchSceneForDimensions

prefetchSceneForDimensions(
    manager: SceneLoaderManager,
    dims: SimpleDims,
    scene: Group,
    loaderId: string | undefined,
    opts: { budgetMs: number; ladderDepth?: number | "auto" },
): void
Fire a background t+1 slice prefetch for a PREDICTED dimension state (dimension playback). Mirror of updateSceneForDimensions, but fire-and-forget and routed to SceneLoader.prefetchSlice — it never moves the real view and is aborted by the next foreground update.
Parameters
- manager: SceneLoaderManager
  The host's loader manager (see loadScene).
- dims: SimpleDims
  PREDICTED dimension state (currentStep advanced to the next playback tick via DimensionAnimationManager.peekNextValue).
- scene: Group
  THREE.Group containing the scene (for maxRadius).
- loaderId: string | undefined
  Optional loader ID, defaults to default loader.
- opts: { budgetMs: number; ladderDepth?: number | "auto" }
  - budgetMs: number
    
    Per-pass LOD time budget for the shadow pass (always set — it is also what makes prefix ladders cacheable).
  - OptionalladderDepth?: number | "auto"
    
    Pinned playback ladder depth; the shadow pass deepens to exactly this many rungs (see ViewState.ladderDepth).
