The CVE record page always showed the plain-text `value` of the CNA description, collapsing its line breaks, lists and indentation. - If the English description has a `text/html` supporting media entry, it is decoded (when base64-encoded), sanitized with DOMPurify using a strict allowlist of formatting, list, table and link elements, and rendered as HTML. Links open in a new tab with `rel="noopener noreferrer nofollow"`. - Otherwise the plain-text description is rendered in a monospace font with `white-space: pre-wrap`, so line breaks, indentation and ASCII diagrams are preserved while long lines still wrap.

Move the sanitizer options into a constant typed with DOMPurify's `Config`, so misspelled option names are caught at compile time. Assisted-By: Claude Opus 5.5 <noreply@anthropic.com>
