REACT_APP_VELT_API_KEY=your_api_key

Generate a high-quality, premium-looking landing page for an AI product using React and normal CSS (no Tailwind or styled-components). The landing page should have a modern and sleek design with an engaging hero section, a compelling call-to-action (CTA), and sections for features, testimonials, and pricing.

The design should feel futuristic, elegant, and visually appealing with a clean UI, smooth animations (CSS-based where possible), and a dark theme with neon or gradient accents. Include:

- Hero Section: Large, eye-catching headline, subtext, and a 'Get Started' button.
- Features Section: Three to four cards highlighting AI product capabilities with icons.
- Testimonials: A section with user reviews and profile pictures.
- Pricing: Simple pricing plans with CTA buttons.
- Footer: Contact info, social links, and company details.

Ensure the page is fully responsive and looks premium on all devices. Use CSS for styling, avoiding frameworks like Tailwind or Bootstrap. Maintain proper spacing, typography, and hover effects for a smooth UI experience.
