Climb into Cantor’s Attic, where you will find infinities large and small. We aim to provide a comprehensive resource of information about all notions of mathematical infinity.

Basically bases all of tiering beyond baseline universal on this. She is a mega autist and wanted to outright get rid of "multiversal" as commonly percieved, but had to lower her power level to make some compromises and not be totally alien.
Main gist is higher infinities are real and mathematically viable and they can be rigorously analyzed, quantified, and qualified in cross-fictional comparisons. Higher dimensions, however, aren't higher infinities, and merely an arbitrarily large series of points across an axis. Dimensional tiering is nonsense because dimensions are nothing but points. It affects volumetric size of a lower dimension, but won't be actually tangibly relevant unless a structure is infinite dimensional, which at that point the volume of something will always be infinite due to some geometric formulas.
It rejects the arbitrary wank of dimensional tiering but it is extremely strict, uncaring, and unforgiving. For example, not even Zen'o in DBS would likely get beyond universal+
