designed for integration into a WordPress site using Elementor.\r\n    It includes a visual product catalog, an interactive weight calculator,\r\n    a detailed pop-up for adding products with specific parameters and images,\r\n    and robust error handling.\r\n\r\n    Key improvements and features for this version:\r\n    - User can now click directly on the product image in the catalog to open the \"Add to Calculator\" pop-up.\r\n    - Product images are now displayed in the catalog instead of placeholders.\r\n    - \"Send List via Contact Form\" button now stores the message in local storage and redirects,\r\n      requiring a small JS snippet on the target contact page to auto-fill the textarea.\r\n    - New sheet products added: \"Cold-rolled Steel Sheet\" and \"Chequered Sheet\".\r\n    - \"Expanded Sheet\" product details and standard sizes have been updated.\r\n    - All calculation formulas, especially for sheets using kg\/sqm and profiles using kg\/ml,\r\n    - have been meticulously verified and are prioritized for accuracy.\r\n    - Removed \"Welding Wire\" and \"Galvanized Profile\" as requested.\r\n    - All user-facing text and comments remain in English for internationalization and translation.\r\n    - Styles are refined for a modern, user-friendly design, aligning with Masivcorp.md aesthetic.\r\n    - NEW: Standard size selection is now available directly in the main calculator.\r\n    - UPDATED: The 'sendToContact' function has been reviewed and slightly optimized for message formatting.\r\n    -->\r\n\r\n    <style>\r\n
