I thought it'd be fun to outline (literally) how much of a hack the custom UI in the recomp is. Anything surrounded by an outline is drawn using Dear ImGui and isn't rendered by the game.

I've been naturally tending toward using more ternary operators and writing more branchless code over time. I find it generally elegant and compact. But it's true that it's a little less easy to debug step into or to set breakpoints for.
