Module origin 

Origin model for rendered documents.

See https://html.spec.whatwg.org/multipage/origin.html. The browser layer uses origins to:

• expose a consistent origin through the window / location / document JavaScript APIs,
• gate access to internal schemes (resource:, …) from web pages,
• compute Origin / Referer request headers without leaking bundled resource URLs to external servers,
• enforce same-origin / cross-origin visibility for fetch() and XMLHttpRequest.
