Add fallback fonts to Themes

As noted in this community post, there isn’t a means of adding fallback fonts in Theme font selection UI. Fallback fonts are a standard best practice, and interestingly, the Design Accessible Content documentation page mentions fallback fonts.

Without it being built in as an option, custom CSS is required to add them to email designer emails. A noted on the custom CSS documentation page, users who choose to leverage custom CSS do so at their own risk and will not be supported by Adobe Support.

To support best practices and ease of use, I’d propose the product team incorporate fallback fonts into the Theme functionality—whether built in behind the scenes for each standard/Google font, or a more flexible user-driven option.
