Author here. I'll take this comment charitably, because it did lead me to discover that I merged the PR well before my Github action to compress images completed. Just re-ran it, and the images are all ~50% reduced in size now: https://github.com/whatrocks/blag/pull/22

Thank you for this nudge. I'm sure there's more I could do here, but hopefully this helps.

The JS bloat is likely the interactive stuff in my "/library" and it's been on my to-do list to fix this. Thanks for this nudge, too.
