She is sitting in the library, studying. It's her most common pastime, by hours; spending time with her sister is more enjoyable but Jaromira prefers to socialize more broadly and Katarzyna would only get in the way. This is better on net; the two of them share a room, so it isn't as though her sister's time is entirely hogged by the other girls who call this boarding school "home." Or at least "prison." Katarzyna doesn't mind it, though; the school library is excellent, and basic manners and care for the books has endeared her to the librarian to a sufficient degree to lubricate the interlibrary loans process when there's something she wants to read that they don't have.
"I've tried non-circles. I didn't vary too far afield, but I did triangles and squares and asterisky things and stars with various numbers of points."
"At least while holding the rest of my outfit constant and the way I happened to implement them, yes."
"Mm-hm! Since I'm not cut out for swarm-fighting I don't worry about it that much, though."
"Swarm fighting is a valuable and necessary public service but it still feels like a waste of time to try to do personally."
"Yes, but you have other reasons to want high performance. I can stop a car and I'm not going to be in a position to stop a kaiju, so I don't need to squeeze every iota of pretty out."
"That's true. I suspect I would be in your position, but more for research purposes than out of a desire for greater specific functionality."
"It's still really interesting what things are objectively magic-pretty and what things aren't! I take laborious data on circle arrangements! It's just not a matter of practical urgency for me."
"It is!!! --It's possible your power will combine interestingly with something--if combinations work--and you might want to optimize harder then, if it happens."
"I don't have nearly enough information to informedly speculate but I have plenty enough to wildly fantasize!"
"Synergize with a healer and stop aging, synergize with someone who does something permanent, if those exist, to stop things and make them stay stopped--I'm thinking less 'permanently anchor an object in place' and more 'and now this object is no longer radioactive'--actually, that's a thought, can you stop radioactivity at all right now, even temporarily, that seems like the kind of thing that would make sense to let the Red Cross know is on the table just in case..."
"I haven't tried that, and my range is okay but I don't know if it's good enough. I probably cannot do it in a radiation suit, see."
"Yes, that makes sense--well, at least some radiation is just electromagnetic waves, like light but much higher-energy, so we could try it with a light?"
"I can in fact turn lights off, I thought of trying that! But I don't know if I'm stopping them at a different point in the process, like stopping electricity going to them."
"I don't have any right now but they can't be hard to acquire! I suspect there are stores that sell them in this mall, it's much more probable than a stylist."
"Yeah, we can probably find some. Let's get the check and go look -" She waves down a waiter.
