 *   "App.svelte",
 * );
 * ```
 *
 * @since 2.0.0
 * @param content - The raw `<script effect>` body content.
 * @param filename - The source filename, used in error messages.
 * @param options - Optional transform settings for generated script code.
 * @returns The transformed code and any block references.
