# Markdown Showcase

This page demonstrates every markdown construct that BBS-MD renders. Use it as a reference or a test page.

## Headers

Headers from H1 through H6 each have distinct styling. H1 and H2 get decorative underlines.

### This is H3

#### This is H4

##### This is H5

###### This is H6

## Text Formatting

Here's **bold text**, *italic text*, and ***bold italic*** combined. You can also use ~~strikethrough~~ for deleted content. Mix them freely: ***~~all at once~~***.

Inline `code spans` render in a distinct color for quick identification.

## Lists

### Unordered

- First level item
  - Second level with different bullet
    - Third level goes deeper
  - Back to second level
- Another top-level item

### Ordered

1. First step
2. Second step
3. Third step
   1. Sub-step A
   2. Sub-step B
4. Fourth step

## Code Blocks

### Rust

```rust
use std::collections::HashMap;

struct BBS {
    name: String,
    pages: HashMap<String, Page>,
}

impl BBS {
    fn new(name: &str) -> Self {
        BBS {
            name: name.to_string(),
            pages: HashMap::new(),
        }
    }

    fn add_page(&mut self, slug: &str, page: Page) {
        self.pages.insert(slug.to_string(), page);
    }
}
```

### Python

```python
class VaultReader:
    def __init__(self, path: str):
        self.path = path
        self.pages = {}

    def load_all(self):
        for md_file in Path(self.path).glob("**/*.md"):
            slug = md_file.stem
            self.pages[slug] = md_file.read_text()
        return self
```

### Shell

```bash
#!/bin/bash
# Deploy BBS-MD as a login shell
useradd -m -s /usr/local/bin/bbs-md bbsuser
mkdir -p /home/bbsuser/vault
cp -r ./demo-vault/* /home/bbsuser/vault/
echo "BBS user created. Connect via: ssh bbsuser@localhost"
```

### Plain (no language)

```
No syntax highlighting here.
Just plain monospaced text in a box.
Useful for ASCII diagrams or raw output.
```

## Blockquotes

> This is a simple blockquote. It gets a yellow pipe border on the left and gray text.

> Multiple levels of nesting work too:
>
> > Nested blockquote. The borders stack.
> >
> > > Three levels deep. Still readable.

## Tables
