Fee-fi-fo-fum—Ligatures and Typekit

Recent viewers may have noticed that Effra, as rendered on this site, had some ugly characteristics (especially fi). At first I had concluded that Effra simply lacked ligatures for the web but a more exhaustive investigation led me to understand that the issue is actually down to Typekit settings. Specifically, all characters need to be selected in the Kit Editor.

Sure enough, once updated (and changes propagated), the text renders tolerably well (at least on the current version of Safari for iOS).
