## Brief

## Look & feel
Deliver a cohesive design system (type scale, color, spacing) before building.

## Tech
- Platform: Next.js (full-stack React)
- Use modern CSS and a lightweight animation approach; avoid janky, layout-thrashing animations.

## Motion direction
- Entrance animations on scroll, smooth section transitions, and meaningful micro-interactions.
- Honor prefers-reduced-motion and keep all content accessible and keyboard-navigable.
- Target 60fps; prefer transform/opacity; lazy-load heavy assets.

## Deliverables
1. The design system + a one-paragraph motion rationale.
2. The complete, runnable code, component by component.
3. Notes on performance budget and how it was met.

Make confident design decisions and explain the key ones briefly.
