- The "bootstrap" didn't give enough credit to everything this module was doing - it's responsible for managing correct initialization and reinitialization of the frontend Routes as well as passing router creation information back to the frontend's URL service
- The refactor is done in two steps - the "bootstrap.js" will be renamed in the follow-up commit to have a clean history of how the file evolved
refs https://linear.app/tryghost/issue/CORE-103/decouple-internal-frontend-code-from-url-module
- By becoming a parameter in the routing bootstrap process URL is Service no longer a "require" inside the frontend controllers but rather becomes a part of the "internal API" of the bootstrapper. This is not the end form of it, rather a step closer to decouplint routing from the URL serivce.
- The bootstrap module needs a facelift to have cleaner distinction between init/start methods. This is left for another time

- Email-only is not considered a general availability feature and can be used without special flags.
- It allows to publish a new post type "email only" that only goes out as an email newletter and is available through an undescoverable URL (does not appear anywhere publicly similarly to preview posts) on the site.

- Relying on uuid instead of slug makes the posts less discoverable and partially soves discoverability through overriden robots.txt files
refs https://github.com/TryGhost/Team/issues/953
- Emails posts should be not explorable by the rest of the frontend similarly to the draft or scheduled posts. Email posts should also keep the content gating, so that specific parts of content can still be gated based on the post's visibility setup
- A separate frontend router was chosen to implement this part of the system instead of a moutable express app due to increased complexity to introduce the latter approach.
- All "sent" email-only posts will be accessible through the `/email/:slug/` route
