```js
const x = 1
```

Global Layers

Top Layer (Above All Slides)

Create global-top.vue:

<template>
  <div class="absolute top-0 left-0 p-4">
    <img src="/logo.png" class="h-8" />
  </div>
</template>

Bottom Layer (Below All Slides)

Create global-bottom.vue:

<template>
  <div class="absolute bottom-0 right-0 p-4 text-sm">
    © 2025 My Company
  </div>
</template>

Scoped Styles

Add CSS for a single slide:

# Styled Slide

<style>
h1 {
  color: #2563eb;
  font-size: 3em;
}
</style>

Special Characters

Emojis

🚀 Rocket launch!
👋 Hello world!

Icons (with UnoCSS)

Best Practices

1. Consistent Frontmatter: Use the same structure across slides
2. Meaningful IDs: Add IDs to slides you'll link to
3. Organize Notes: Keep speaker notes concise and actionable
4. Use MDC Sparingly: Don't overuse inline styles
5. Test Separators: Ensure blank lines around ---
