+/**
+ * Improved Amazon metascraper plugin that fixes image extraction.
+ *
+ * The default metascraper-amazon package uses `.a-dynamic-image` selector
+ * which matches the FIRST element with that class. On amazon.com pages,
+ * this is often the Prime logo instead of the product image.
+ *
+ * This plugin uses more specific selectors to target the actual product
+ * image:
+ * - #landingImage: The main product image ID
+ * - #imgTagWrapperId img: Fallback container for product images
+ * - #imageBlock img: Additional fallback for newer Amazon layouts
+ *
+ * By placing this plugin BEFORE metascraperAmazon() in the plugin chain,
+ * we ensure the correct image is extracted while keeping all other Amazon
+ * metadata (title, brand, description) from the original plugin.
