+  "details": "Use for fashion/apparel e-commerce with product variants. Card displays product image with favorite toggle at top. Below shows product name and variant description (e.g., 'Dark Grey  3 Colors') stacked vertically on left, with price aligned to top right. Clean, minimal layout ideal for clothing, accessories, and variant-heavy products. Automatically switches between grid (1-4 items) and carousel (5+ items) modes. Carousel offers auto-scroll or button controls (recommended: keep default buttons for better UX). Optional header with title, description, tag, and buttons. Header supports all textbox layouts (default, split, split-actions, split-description). Supports inverted background with shouldUseInvertedText utility for proper text color in cards.",
