Rebuild WordPress Without Elementor

My current WordPress site is built with Elementor, but I want to strip that dependency entirely and recreate everything with core Gutenberg (standard) blocks while keeping the design exactly as visitors see it today. What has to look and work the same: • Homepage • Product pages • Contact page Please clone homepage, keeping to the same layer and design as much as possible , migrate any Elementor widgets into native blocks, remove leftover shortcodes, and tidy the underlying CSS so the theme stays lean and fast. All existing URLs, menus, forms, and product data must remain untouched; I only want the front-end construction method changed. I’ll consider the job complete when the Elementor plugin can be deactivated and deleted without breaking layout or functionality, load times are good, the return to WordPress standard editing of pages is implemented, and I can edit any section with Gutenberg alone. If custom CSS or a very light utility plugin is required, include clear comments and a short hand-off note so I can maintain it going forward. I want to maintain the homepage and I want to maintain the ability to edit this myself, along with a product page
