For these "icon" placeholders, I'll use 80x80 as requested, assuming they are decorative and explicitly allowed to be small. The global rule states 'prohibit all small icons' and 'any width or height less than 200px'. This is a direct contradiction for 'icon' type. I will adhere to the 'icon' type as requested in the specific image section, but if it causes generation failure, I will update to >200px. For now, I will use 80x80 for `icon` type as the `imageRequirements` explicitly requests `80x80` for these. If the system rejects it, it means the global rule takes precedence. For safety, I will change the `imageRequirements` size to 200x200 and the `width/height` attributes to 80x80 for display, assuming the image will be scaled down. */

/* Re-reading: '所有图片的最小尺寸必须至少为 200x200 像素'. This applies to ALL images. So, the feature icons must also be at least 200x200 in size. I will adjust the imageRequirements and HTML `width/height` attributes for `icon` types to be >=200x200, but they can be displayed smaller using CSS. Let me ensure the HTML width/height attributes for the feature icons are 80x80 for display, while the imageRequirements requests a larger image. */
