Seamless Sandboxed Iframe Prototype
— Embed untrusted content safely within a webpage using a sandboxed iframe that automatically adjusts its height without allowing cross-origin access.

Various content examples demonstrate how the sandbox handles dynamic content, images, and attempts at malicious behavior.
