Build me a modern landing page template for a startup or personal project. I want it to feel clean, polished, and easy to customize, with a strong hero section, clear calls to action, feature sections, testimonials or social proof, pricing or highlights if they fit, and a footer.

Make it fully responsive and work well on mobile, tablet, and desktop. Include a light and dark mode toggle, and use a nice component based design system so the page feels consistent and professional. Keep the content as placeholder copy and placeholder images so I can swap in my own brand later.

Use the latest Next.js setup with Tailwind styling and shadcn style components, and make the whole thing easy to edit from the main components. If you need to check current docs online for anything, go ahead. I just want a beautiful landing page I can open, run, and then quickly personalize for my own product.
