Tighten Remarkup and Fontkit CSS rules in Phabricator
Summary: Fixes T5497. Scope these down a little bit so they don't bleed into {W...} embeds and such.
Test Plan:
- Viewed a Legalpad document with headers, monospaced stuff, and lists. Looked the same before/after.
- Viewed a comment with headers, monospace, and lists. Looked the same before/after.
- Viewed a {W..} embed, now looks sane.
