The email was branded "La Suite Numérique",
we updated the template to make it generic, we
will use settings env variables to customize the
email for each brand.
The emails were too big, gmail by example was not
able to display them correctly.
It was caused by base64 image, so they are
replaced with a link to the image.
We fixed the link to the website, it will improve
the score of the email.
Add a gouv logo image to the public assets folder.
We will be able to access it via the frontend url.
Usefull to get them from our templates on the
backend side.
Add a offline mode support from a service worker.
The service worker will cache the assets and the
visited pages to be able to work offline.
Created a fallback page for when the user is offline
and tries to access a page that is not cached.
