FEAT:Homepage "Explore AMP success stories" section appears visually sparse

## 🚀 Feature Request

### Problem
The "Explore AMP success stories" section on the homepage (amp.dev) currently consists only of text and a single button, leaving significant empty space. This creates a visually unbalanced layout and misses an opportunity to immediately showcase AMP's impact to visitors.

## Current State
- Large empty areas around the text
- No visual elements or previews of actual success stories
- Minimal engagement despite being key social proof content

### Solution
Transform this text-heavy section into a visual showcase:
- Add company logos and their success metrics
- Include eye-catching numbers and stats
- Use icons or small graphics to break up the text
- Make it look like a "hall of fame" for AMP users

### Alternatives
1. Keep it simple - just add icons
Add simple icons (⚡ for speed, 📈 for growth) next to the existing text

2. Add just one featured case study
Highlight one major company's success story instead of multiple
Less complex than a full carousel or multiple cards

### Additional information (optional)

Why this matters:

This is one of the first sections visitors see on the homepage

It's meant to build credibility but currently lacks visual impact

Empty space makes the page feel incomplete

I'm new to open source and would appreciate any guidance on:
Where the success story data is stored in the codebase
The project's design system/component library
Whether there are existing visual elements I could reuse

Start at the "Explore AMP success stories" section on amp.dev and locate the homepage source, the success-story data, and reusable components from the project's design system. Review the available content and agree on one visual direction before implementing it; done means the section presents meaningful success-story visuals and no longer appears visually sparse.
