/* Note: Since we have local images, we should check if 'hero.jpg' exists in Solar_BE/images. Yes it does.
   However, the previous code had 'https://solarstock.be/img/cms/banner-solarstock.jpg' in CSS.
   We replaced main product image, but not this background image.
   Wait, the user previous instructions were to fix BROKEN images. Background images might be broken too.
   I should probably use a dark gradient only or try to download the background image if I can.
   For now, I'll stick to the dark gradient effectively, maybe just 'background: var(--secondary-color);' if image fails.
   Or use the product image as background with heavy overlay?
   Let's use the dark blue gradient as a safe premium fallback. */
