* Add route for comment social preview
* Add method comment to social_previews_controller
* Add view for comment social preview
* Fix spacing in meta keywords
* Update comments page keywords
* Create helper for comment social media image
* Use comment social image, add published condition for article social image
* Add tests for comment social preview
* Remove not_found fallback for social previews controller
* Remove cached_tag_list
* Update typos of word 'image' in spec
* Add failing tests for social previews controller. HTML changes between
requests, which breaks caching.
Since we use the HTML to generate the cache key. When the views have any
randomness in them, it breaks the cache, which means we regenerate
images on each request, rather than using what's in memcached.
Adding test to protect from regressions
* Fix randomness in social card templates
The aria tags are randomly generated. Since this is for rendering
images, they aren't needed.
* Make the linter happy by using the sanitize helper
* Add HtmlCssToImage for generating images
This will be used by social_previews to convert the templates into images.
Setup a fallback image primarily for local dev, so that this won't cause
errors if authentication is missing.
Caching is setup to use contents of the html/css. So it with
autobust/generate a new image whenever the markup changes.
* Update Article social preview template to not be random
+ Being random breaks caching (since we generate cachekey by a SHA of html content)
+ Use Roboto for when generating via HTML/CSS to Image
* Update Tag social preview template to not be random
+ Make rand deterministic so it doesn't break caching
* Update user social preview template for html/csstoimage
* Update shecoded template to work with both url2png and htmlcsstoimage
* Add ability to respond to .png for social previews controller
When adding .png to the url, these routes will now generate an image and
redirect to it.
This leaves the existing pages as they were, so we're backwards
compatible with all the existing links out in the world.
