Chuibility/inspinia — reverse-engineered prompt

I want a polished, responsive admin dashboard demo based on this Inspinia theme repo. Please use the simplest version that can run locally without a lot of setup, probably the plain HTML version unless you think another included version makes more sense. Make it feel like a real app backend with a main dashboard, charts, tables, forms, calendar, mailbox or file manager style pages, login and error screens, a landing page, and a handful of reusable UI components.

Keep the layout clean, mobile friendly, and easy to click through. I want working navigation, sample data, and the main widgets and interactive pieces hooked up where possible so it feels like a complete demo instead of loose pages. If some folders are only starter templates, choose one full version and get that running properly.

Please also add a short README that explains how to open or run it locally, and keep the licensing note obvious since this seems to be a study or demo copy and not something to use commercially. You can look up current docs online if needed.
