arhamkhnz/next-shadcn-admin-dashboard — reverse-engineered prompt

Build me a clean modern admin dashboard starter like a polished SaaS back office. Use Next.js 16, TypeScript, Tailwind, and shadcn UI. I want it to feel minimal, responsive, and ready to customize, not cluttered.

It should have a main dashboard layout with a collapsible sidebar, top bar, content area, and layout controls. Include several ready made dashboard pages such as default, CRM, finance, analytics, productivity, ecommerce, and academy. Add login and authentication screens so the app feels complete. Please include theme switching with light and dark mode plus a few color presets like neutral, tangerine, brutalist, and soft pop.

Add common admin building blocks like cards, charts, tables, forms, filters, and settings style pages using sample data. Keep the code organized so each feature keeps its own page and components, and shared UI stays reusable. Make it look production quality and deployable on Vercel. Look up current docs online if needed.
