As a curious reader I want to see related articles after I'm finished reading so that I can learn more.
* Show up to 3 article cards after end of article, before Wikipedia footer.
* If no related cards are available do not show the read more heading
* Related articles should not impact first paint time.
* Articles shown using same backend as apps "Read more"
* The feature should be featured flagged and turned on only in mobile beta to begin with
* The feature should show up in desktop and should be usable. It does not need to look great (we will work on desktop and the beta feature in the next sprint).
* It only shows it on pages in the main namespace
{F159450}
Cards are identical to those in Gather and show:
* page image
* text extract (first 3 lines of text from article)
background behind cards and Wikipedia footer #EDEDED
Before implementing as a team it would be useful to discuss how Gather and Read more can share css/templates for such a feature.
Code should live in the RelatedArticles extension and should not interfere with existing code there.
