Act as an expert frontend developer and UX/UI designer. I need you to build a premium, high-performance landing page for a sports nutrition brand named "JUICED".

Product Context: JUICED makes premium workout sour strips. The core formula swaps Haribo's glucose syrup and gelatine for dextrose and rice syrup (identical glycemic index, cleaner label) plus fruit pectin instead of gelatine (making it vegan, same chew texture). Colour comes from natural extracts, not Red 40. Every 50g single-serve pouch delivers exactly 30g of fast-digesting carbs for precise, measurable fueling.

Tech Stack:

Design System & Aesthetic (Immersive UI):

Section-by-Section Requirements:

  1. Navigation: Fixed at the top with mix-blend-difference. Include a bold logo ("JUICED"), center links (The Science, Macros, Shop), and a hollow neon-yellow "Order Now" button.
  2. Hero Section (Split Layout):
  3. Infinite Marquee: Use Framer Motion to create a seamless infinite scrolling bar. Background should be faint translucent gray. Text should alternate between "The Formula of Champions" and "Precision Macros" separated by Lucide icons (Activity, Zap).
  4. The Math (Macros Section):
  5. The Formula (Bento Grid): A grid of 3 translucent cards showcasing the value props. Each card needs a Lucide icon inside a dark frosted square, a bold title, a paragraph, and a bottom monospace tag.
  6. Footer / Bottom CTA: Centered layout with immense typography ("Get Juiced."), a short paragraph, and a large neon-outlined CTA button. End with a simple copyright/legal footer at the very bottom.
