At some point (years ago?) my safari starting not having some fonts. Example is this page: http://flask.pocoo.org/docs/deploying/others/
How can I fix this?
Solution: I looked in ~/Library/Fonts and there were a bunch of fonts with odd names (from a bad rsync years ago where characters somehow became html escaped).
I deleted the entire contents of that directory and everything cleared up, although I still can't find Garamond anywhere on the system. But it definitely is available.
