// Title: Barcode Quality Settings Reset Demonstration
// Description: Generates a Code128 barcode, reads it with a custom high‑quality setting, then resets to default to show CPU usage restoration.
// Prompt: Validate that resetting QualitySettings to defaults restores original CPU consumption patterns during processing.
