- The files in the public folder are all specific to the frontend:
- ghost.css / ghost.min.css contains styles for default templates like unsubscribe, private and error
- favicon is the default for the frontend
- robots.txt is the default robots.txt for the frontend
- sitemap.xsl is the stylesheet for the sitemap
- Therefore, they should live in the frontend!
refs #8221
Instead of serving our shared assets from a `shared/` folder, we move the file, which are used server side to `server/public`.
Adds a new `config.paths` entry: `publicFilePath` and renames the middleware to serve the files to reflect the changes.
Adds `404-ghost.png` images to be used by the server side rendered default template `error.hbs`.
