If the website loads successfully, identify and list at least three main product categories (e.g., 'Spices', 'Sauces', 'Snacks'). If the website continues to display a '404 Not Found' error or any other error indicating inaccessibility, state that 'The Royal Gourmet Corp. website remains inaccessible.'
