/**
* 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.
