iris-aiandClaude Opus 5 f11f5f4825 Divide twice in a range's inverse, not four times ...

Which end of the answer each bound comes from is known from the sign of the
fraction before dividing; taking the min and max of four divisions asked the
question twice. A division is the most expensive thing in that function and
it runs per child per axis.

`many` 0.283 ms a frame to 0.278. Small, and strictly less work.
