feat: Landing page design improvements

Based on landing-page-design skill principles:

Homepage:
- Redesigned hero with outcome-focused headline ("Transform Your Hair & Skin")
- Added social proof micro (5 stars + 50,000+ customers)
- Better CTA: "Transform My Hair & Skin" instead of "Shop Now"
- Added trust indicators in hero (30-day guarantee, free shipping, cruelty free)
- Added ProblemSection to create empathy (dry hair, confusing ingredients, no results)
- Added HowItWorks section (3 steps: Choose, Apply, See Results)
- Improved AsSeenIn with scrolling marquee on dark background
- Premium trust badges with stats and icons

Product pages:
- Improved CTA: "Transform My Hair & Skin" (action verb + value)
- Added ProductBenefits section (4 key benefits)
- Added ProductReviews section with customer testimonials
- Added AsSeenIn scrolling banner
- Added trust indicators with icons

Section order now follows proven conversion sequence:
1. Hero (headline + outcome + CTA)
2. Social Proof (trust badges, logos)
3. Problem (empathy)
4. Solution (products)
5. How It Works
6. Testimonials
7. Final CTA
