Page-by-Page Build

Based on the approved concept, build the [Homepage/About/etc.] page.

Constraints:

• Single-file React component with Tailwind
• Mobile-first, responsive
• Performance budget: no library over 50kb unless justified
• [Specific interaction from Phase 1] must be the hero moment
• Use the frontend-design skill for design quality

Show me the component. I'll review before moving to the next page.
