description: "Parametrically transforms complex letterforms into simplified geometric shapes like circles, triangles, and squares. This transition can occurs through gradual structural shifting and/or character swaps at specific intervals."

Other description proposal: "Reduces the typeface from idiosyncratic humanist forms toward strict geometric forms. Adjustments range from subtle shape-shifting to full character alternates across the axis."

Can we change “parametric” to “Allometric” ?
Allometric (allo- "other/different" + -metric "measure")
“In biology, this describes parts of a system growing at different rates.”

Yes - since we have Font Bureau "Parametric" axes, we should avoid that term :) But we can just remove that word and its fine.
