Hi Nick excited for a novel question! Short answer is we do NOT.
The two things I can think of that might help are using some form of non-px based units to enforce a specific aspect ratio. You can use any valid CSS unit in Replo :)

I was able to make the images grow as the width of the page grew, had to make sure the wrappers were set at 100% width, images 100% width - height: auto
I like that idea!
Sounds like it worked well and that is inline with our standard Responsive Design concept where if you have things setup with 100% width (or fill-available width), the setup will change as the screen size changes (and therefore what "100%" or "available width" actually represent changes)
We have some docs responsive design here:
