Frequently asked questions

Does the preview render raw HTML?

The preview uses a limited renderer and sanitizes link destinations; it is not intended as a full HTML renderer.

Are tables supported?

Markdown tables are not listed among the supported blocks. Use headings, paragraphs, and lists for predictable previews.
