Readers cannot interact with dynamic, calculation-based tools embedded directly in a single article, because custom scripts can currently only run site-wide through Custom HTML integration, and script or style tags placed directly in article content are sanitized for security.

Add a supported, sandboxed way to embed custom interactive HTML, CSS, and JavaScript scoped to one article, similar to the existing Custom code section available for the knowledge base home page, so authors can build in-article tools such as calculators or dynamic widgets without external hosting or site-wide script changes.

Benefit: Authors could offer hands-on, interactive tools directly inside the relevant article, letting readers perform calculations or other dynamic tasks in place while reading, without leaving the page or relying on a separately hosted page.
