Optimize a product photo and compose it into a promotional banner. First, use transform_image to resize and optimize [product image URL] for web. Then, use generate_image to create a banner with these layers:
1. Background: gradient layer with [brand colors]
2. Product photo: image layer with the optimized product image
3. Sale text: text layer with [sale message] in large bold text
4. Price: text layer with [price] and [original price] strikethrough
