+/*!
+ * MlingDisplay — client-side port of mingling_cli/src/utils/display.rs
+ *
+ * Parses the same markdown-ish markup used by `display.rs` and returns HTML
+ * with the equivalent ANSI styling applied as CSS classes / inline colors.
+ *
+ * Supported syntax:
+ * - Bold: **text**
+ * - Italic: *text*
+ * - Underline: _text_
+ * - Cyan: <text>
+ * - Inline code: `text` (green)
+ * - Colors: [[color_name]] ... [[/]] (nested)
+ * - Escapes: \* \< \> \` \_
+ * - Headings: # Heading 1 ... ###### Heading 6
+ * - Blockquote: > text
+ *
+ * Exposes: window.MlingDisplay.parse(text) -> HTML string
