Package size limit?

Hi,
I’m about to submit a package for my newly created channel. I’ve check the Certification for submitting a channel and thing that bother me most is the 4MB limit.
Is it has to strictly be under 4MB? Since I want to include some asset (custom fonts, images,…) in the channel so the size would be over 5MB.
If it has to be under 4MB then is there any other way to include heavy custom asset?

Thanks in advance.

You’d likely get a faster (and better) response asking on the developers forum. This one is really just for end users, and very few of us have any idea how that works.
