coreui/coreui-free-bootstrap-admin-template ? reverse-engineered prompt

Build me a clean responsive admin dashboard website using CoreUI and Bootstrap 5, with the same kind of polished look and feel as a modern admin template.

I want a sidebar, top navbar, dashboard home page, basic analytics cards, tables, charts placeholders, forms, icons, login and error pages, and a few reusable UI sections so it feels like a real starter template. Make it easy to customize, with tidy styles and organized pages, and make sure it works well on desktop and mobile.

Use the existing project structure and keep the code simple and consistent. If you need to check the latest CoreUI or Bootstrap docs online, go ahead. Also make sure the build and start commands work smoothly, and that the final result looks professional out of the box.
