## Overview

Successfully implemented a modular, type-safe landing page template system that allows creators to build professional landing pages without code. The system is built on Astro 5 + React 19 + Tailwind v4 and follows the ONE Platform's 6-dimension ontology.

## Architecture

### Layer 1: Type Definitions (`src/types/landing-page.ts`)

Complete TypeScript interfaces for all page components:

- **BrandingConfig** - Customizable colors, logo, favicon
- **Section Types**:
  - HeroSection - Hero with CTA
  - FeaturesSection - Feature grid (2, 3, 4 columns)
  - TestimonialsSection - Social proof with ratings
  - HowItWorksSection - Process steps
  - CTASection - Call-to-action
  - FAQSection - FAQ accordion
  - FormSection - (Ready for implementation)

- **LandingPageConfig** - Complete page configuration
- **Component Props** - Type-safe component interfaces

### Layer 2: Components (`src/components/landing-page/`)

Six reusable, responsive Astro components:

1. **HeroSection.astro**
   - Dynamic backgrounds (image, video, gradient)
   - Customizable headline, subheadline, CTA
   - Responsive typography scaling
   - SEO-friendly structure

2. **FeaturesSection.astro**
   - Grid layout (2, 3, or 4 columns)

3. **TestimonialsSection.astro**
   - Two layouts: grid and carousel
   - Star rating support
   - Author avatars
   - Accessible card design

4. **HowItWorksSection.astro**

   - Optional step images
   - Connection arrows
   - Timeline summary

5. **CTASection.astro**
   - Dual button support (primary + secondary)
   - Background image support
   - Centered layout
   - Gradient backgrounds

6. **FAQSection.astro**
   - Accordion pattern (via FAQAccordion client component)
   - Smooth expand/collapse
   - Mobile-optimized
   - No JavaScript required

### Layer 3: Demo Page (`src/pages/landing-demo.astro`)

Full working example showcasing:

- All sections in action
- Configuration-driven rendering
- Dynamic section mapping
- Branding system integration
