Fix Oblivious skin summary remarkup and partially fix title

Summary: Ref T9546. I only got the title to always show the blog title (better than nothing) -- showing the post title properly isn't trivial and is more work than I want to do right now.

Test Plan:
  - Description now has remarkup.
  - Title now shows blog title (better than nothing).
