I was going to complement OP on how amazing this feels, not realising the drawing was lifted from somewhere else.

Seems like a glaring omission to mention Cloudflare D1 and... SVG, but not the guy who did the drawing part of your drawing app

It is a glaring omission with no excuse. I should have mentioned it.

I don't think it's such a big deal. It's a very well known package. The main reason I mentioned him was that it might be a nice/friendly thing to do.
