Product preview card challenge

Approached this mobile first: happy with the code for mobile design (although Chrome seems to cache only the biggest loaded image available from the html srcset and overrides that img tag with whatever is cached at the time) but coding the queries for the desktop design looks a little flimsy and not something I think would scale particularly well. Did I set myself up poorly with the mobile design or is there a simpler solution for the desktop queries that I've overlooked?
