As a Discord user, I want to see interesting previews for links I share, so that my friends and I can properly assess if we'd like to follow shared links or not.
Acceptance Criteria:
- Address following feedback:
- Images sometimes distorted
- Feel like Breaking News should look a little different. If it's breaking news, it'll have more attribution signals than usual, so maybe they especially should be included, since that'll strengthen the preview even more
- Only use big image and not thumbnail
- When no image, show full wikipedia logo instead (same lock-up as the website with globe left and wordmark+tagline right) as the standard placeholder when there is no image article. No thumbnail
- Shorten lead paragraph to 5 lines max
