	export function sanitizeFileNameForAssembly(filename: string): string {
	const lastDotIndex = filename.lastIndexOf('.')
	// if there's no extension, sanitize the whole filename
	if (lastDotIndex === -1) {
	return filename.replace(/[^a-zA-Z0-9_-]/g, ' ')
	}
	const name = filename.slice(0, lastDotIndex)
	const extension = filename.slice(lastDotIndex + 1)
	const sanitizedName = name.replace(/[^a-zA-Z0-9_-]/g, ' ')
	return `${sanitizedName}.${extension}`
