Embeddable FAQ across different Galaxy repo sites

The GTN FAQ are awesome for sustaining text in multiple places
However, communities might have a training page + Community page + subdomain instance, so 3 different places some of the same text may need to go.
It would be nifty to have embeddable FAQ across pages

The issue names no files, tests, or entry points. Start by locating the existing GTN FAQ and the templates or pages that publish it across the training, Community, and subdomain sites; done would mean one FAQ source can be embedded in each requested site without duplicating text.
