What it does

• GitHub-flavoured Markdown out of the box: tables, task lists, alerts, footnotes, <details> and the HTML that READMEs use.
• Built for AI chat: stream an answer as it arrives, fold a model's reasoning, and use a compact chat preset.
• Code, images, diagrams and math: copy buttons and syntax highlighting, a zoomable lightbox, SVG, Mermaid and LaTeX, all in .NET.
• Three presets that look like GitHub, a chat app or a documentation site, in light, dark and high contrast.
• Selection, copy and find across the whole document, with copy as Markdown and HTML.
• Accessible: keyboard navigation, screen reader roles, WCAG AA colours, right-to-left text.
