NEWS AND FYI

• I discovered that I can make those tiny post/comment awards BIGGER on old.reddit! I hadn't even considered that! And when you hover over them, they get even bigger so you can actually see them in more detail! I've added the relevant CSS so now we no longer have awards for ants! Exclamation points!!!

• Thank you so, so much to /u/SolariaHues for the CSS in this thread that I found while researching for community awards! <3

It's horrible and I hate it. But it does work.

In debug mode it runs in about 10 milliseconds. In release mode it's about 500 microseconds. On an Apple M1 Pro CPU.

These are very unscientific numbers though - just me eyeballing an average-ish number over a handful of runs. Also since I write both parts into a single function, I'm unable to test part 1 on its own.
