+This is a sample blog post to validate that content collections are working correctly.
+
+## Features
+- Markdown content with frontmatter validation
+- Type-safe schema with Zod

+## Code Example
+```typescript
+const greeting = "Hello, World!";
+console.log(greeting);
+```
+
+This post will be replaced with real content later.
