Create download blob on-demand

Not sure what the best way to do this is. Currently, a new blob download href is being generated every time the text changes, which is obviously not ideal. ChatGPT recommended something like adding an ephemeral tag to perform the download but I don't like that. See if there's a way to generate that blob URL on demand, or otherwise determine if blob url generation is cheap enough to ignore this.

Looks like it might be slow: URL.createObjectURL() is slow

First answer here is the hidden <a> tag, but looks like there might be some other solutions here: JavaScript blob filename without link
