I was slightly disappointed of them still being labeled as "side notes" even if they were at the bottom

Heh. I guess one could have some fun with a ::before {content: "Side" or "Foot" } inside each breakpoint's media query.

Yeah, there is room for improvement there.

so multiple tiny payments instead of a big one to avoid the fees?
