Technical details

Markdown is ideal for drafts; HTML is what browsers render. We parse with marked and sanitize with DOMPurify before injecting preview HTML to reduce XSS risk from untrusted notes.

Output is a fragment suitable for CMS fields. Full document chrome (html/head) is omitted on purpose.
