[nitpick] The Boot method is currently empty; consider removing it if not needed or adding a comment to explain why it's intentionally left blank for clarity.

Suggested change

	// The Boot method is intentionally left blank as it is not currently needed.
	// It may be implemented in the future if additional bootstrapping logic is required.
