How can I include a piece of custom JavaScript on some (or all) JIRA pages? In particular, I'd like to modify the Rapid Board cards. I'd love to be able to customize them with the fields I care about, but the next best thing is to be able to change their styling to better suit my needs. Right now, I use tampermonkey to implement my changes, but this is a pain to distribute to my team (especially if it needs to change).
