**Plain Text Email Renderer** — convert HTML email bodies into readable markdown.

Email HTML is a hostile environment: table-based layouts from 2004, tracking pixels,
Outlook conditional comments, deeply nested reply chains with inconsistent quoting.
pter converts all of it into clean, readable markdown.

## Usage

```rust
let html = r#"<h1>Hello</h1><p>This is an <strong>email</strong>.</p>"#;
let markdown = pter::convert(html);
assert_eq!(markdown, "# Hello\n\nThis is an **email**.");
```

## What it does

- Converts HTML elements to markdown equivalents (headings, links, lists, emphasis, code, images)
- Unwraps table-based email layouts (single-cell tables become content, multi-column linearizes)
- Detects and normalizes reply chains into `>` quoted markdown
- Strips tracking pixels, invisible elements, and Outlook conditional comments
- Produces output that is readable as plain text and renderable by any markdown toolchain

## What it does not do

- Parse MIME email structure (use `mailparse` or `mail-parser` for that)
- Extract article content from marketing templates (compose with a separate extractor)
- Render markdown to a display format (use `pulldown-cmark`, `comrak`, etc.)
