MD046 - Code Block Style

Rule ID: MD046
Aliases: code-block-style
Category: Formatting
Severity: Warning
Auto-fix: Yes

Code block style should be consistent.

Why This Rule Exists

Markdown supports both fenced code blocks (triple backticks) and indented code blocks (4 spaces). Consistent style improves readability.

```rust
fn main() {
    println!("Hello");
}
```

    fn main() {
        println!("Hello");
    }

```python
print("Hello")
```

    # Indented code block
    echo "World"

```python
print("Hello")
```

```bash
echo "World"
```
