Fireworks don't work for solo category

b/c we do all the fireworks magic in the score header. Which has zero height in solo category mode.

At one point once upon a time (in the same hue-rotate discussion 😆) we tossed around the idea that fireworks would only happen on all category 100s anyhow, so we might want to do that instead of fixing this? 🤷‍♂

ya I could buy that. But in this post-plugin world, who are we to say what constitutes "all" categories? :P

jk, we could do fireworks -> only if 100s on all core categories.
