The problem is that whole thing should have been its own script, which it coulda been with npm-run-all:

https://github.com/mysticatea/npm-run-all/blob/HEAD/docs/npm...

"scripts":{ "buldrun":"run-p check test docs && run-p zip zip:firefox" }

I guess you can put `bun run --parallel` into the script too but it's a bit more verbose.
