I've got a stacked label with multiple fields that I've been building in Arcade. Is there a way to add a halo to just some of my text, via tags or another means? Right now the whole thing is haloed, but I only want the top line to have that effect.

Nothing in the tags, HTML doesn't work.
Your only options seems to be creating two label classes. But then they will be positioned independently from each other. You can force them into the format you want with a a bit of fiddling.
For points, it's easy: the haloed class on top, the other class on the bottom:
For polygons:
You could also post an Idea to include HALO and _HALO label tags in ArcGIS Pro.
That's a good idea to post as an idea - maybe I will! Thanks! I wound up abandoning the halo idea and went with simple boxes.
I created an idea for this, glad to see someone else has interest:
