Functionally looks good, nicely done! 🎨

Requesting changes on a bit of refactoring to make the styles more clear.

@JoshuaKGoldberg The 'Deploy Preview' check has failed even before I committed the requested changes (when I merged master to my branch), but I'm not authorized to open Netlify to check the error. Is there another way for me to verify that? Thanks!

...huh, that's a new one.

Does that happen for you? I'm traveling right now and blocked from trying it locally on #5113.

[marjys]

I can see this error locally now! It seems to be happening due to Eleventy not being able to parse the properties of an object on the Jsdocs api at /lib/reporters/base.js, line 230 (didn't catch it before as I was running npm start docs.watch and it does not build before serving, so I was serving an old version of my build, my fault).
I was thinking about some ways to fix this:

1. Simply replace { message: string, msg: string, stack: string } with Object
2. As we know what the Object structure is, we could add a type definition to it with something like the following, and then replacing the object with FullErrorStack:

 * @return {FullErrorStack}

...

/**
 * An object containing the full error stack results
 * @private
 * @typedef {Object} FullErrorStack
 * @property {string} message
 * @property {string} msg
 * @property {string} stack
 */

So please let me know your preferences and whether we should be opening those changes in another PR or if we could just apply them on this one.
Thanks!

Nice investigation! 👏

Does that happen for you on the master branch? If does (i.e. is not unique to this PR) then yeah, that'd be a separate issue & PR. Yes please!

If it's unique to this branch (?!) then it'd be something to fix here.

[marjys]

The error happens on master too:

Ok, I'll be opening an issue for this. Thanks a lot!

Requested changes were applied and all checks are passing after fix on #5116.
