Announcing AMP Real URL

Introduced AMP Real URL, a feature that allows AMP pages served from caches (like Google's AMP Cache) to retain their original URL in the browser's address bar. This is achieved through cryptographic signing of the content provided to the AMP crawler, leveraging Web Packaging and browser support (initially Chrome on Android). This feature aims to improve brand protection, simplify analytics, increase screen space by removing the 'grey bar', potentially reduce bounce rates, and ensure content authenticity by cryptographically signing the content.
