Build me a premium futuristic AI super app website called NEXUS AI.

I want a polished landing page, login and signup screens, forgot password flow, a main dashboard, pricing page, team workspace, and an admin panel. The app should feel like one place for AI chat, image and video generation, content writing, code help, branding, learning, finance tracking, automation, and team collaboration. Make it look sleek and modern, with a dark futuristic style, glassy cards, neon blue and purple accents, smooth animations, and a really clean mobile friendly layout.

Please include a working theme toggle, responsive navigation, modal and toast interactions, basic form validation, and simple local storage based authentication and chat history so the demo feels usable. Add a nice sidebar in the dashboard, sections for analytics and tools, and make the whole thing feel like a premium product someone would actually want to sign up for. If you need current best practices for anything, look them up online first.
