Panini templating skipping font declarations on in-page variables on iOS devices

Note: I'm using the most recent Zurb Stack for this project.

I've got a master template for an email which utilizes in-page variables that are initialized within the page's front matter in accordance with the Panini docs.

The issue is occurring in the "Class Topics" section of this email template.

All the variable data is being inserted from the front matter correctly; however, I've noticed that one of them consistently doesn't get its font correctly defined according to my scss. This seems to only occur on iOS devices. Other clients are not affected.

Litmus results (Note the device names at the top of each image.)

The results on the iOS devices display one of the items in the $body-font-family font instead of the family I have declared in app.scss.

Similar results occur when I was using Panini's <#each item> method to insert the variables.

Below are is my Inky markup and scss. I've individually declared the font's for classes to make sure this wasn't a scss compilation issue.

Apologies for the non-abbreviated code, but I want to make sure this issue isn't being caused by something else in the markup.
