+## Slide Separator
+
+Use `---` with blank lines before and after:
+
+```md
+# Slide 1
+
+Content
+
+---
+
+# Slide 2
+
+More content
+```
+
+## Headmatter (Deck Config)
+
+First frontmatter block configures the entire deck:
+
+```md
+---
+theme: default
+title: My Presentation
+lineNumbers: true
+---
+
+# First Slide
+```
+
+## Per-Slide Frontmatter
+
+Each slide can have its own frontmatter:
+
+```md
+---
+layout: center
+background: /image.jpg
+class: text-white
+---
+
+# Centered Slide
+```
+
+## Presenter Notes
+
+HTML comments at end of slide become presenter notes:
+
+```md
+# My Slide
+
+Content here
+
+<!--
+These are presenter notes.
+- Remember to mention X
+- Demo the feature
+-->
+```
+
+## Code Blocks
+
+Standard Markdown with Shiki highlighting:
+
+````md
+```ts
+const hello = 'world'
+```
+````
+

+````md
+```ts {2,3}              // Line highlighting
+```ts {1|2-3|all}        // Click-based highlighting
+```ts {monaco}           // Monaco editor
+```ts {monaco-run}       // Runnable code
+```ts twoslash           // TypeScript types
+```
+````
+
+## LaTeX Math
