ColorlibHQ/AdminLTE — reverse-engineered prompt

Build me a polished admin dashboard template like AdminLTE, using Bootstrap 5 and plain JavaScript, with no jQuery. I want it to feel modern, clean, and easy to customize, with a collapsible sidebar, top navigation, cards, charts, tables, forms, alerts, and all the usual admin pieces. It should be fully responsive so it works well on phones, tablets, and desktops.

Please include both light and dark mode, and make the layout ready for RTL support too. I also want a handful of realistic demo pages, like dashboard home, calendar, kanban board, chat, file manager, mailbox, profile, settings, invoice, FAQ, login, register, and simple error pages. Add a multi step form wizard and a data table page as well.

Keep it as an HTML and Bootstrap based starter that someone can copy and reuse for different projects. Make the code tidy and easy to follow. If anything is unclear, check the current AdminLTE docs and demo online and match that overall experience.
