| const clamp = (num, min, max) => Math.min(Math.max(num, min), max); | |
| const repeat = (t, m) => clamp(t - Math.floor(t / m) * m, 0, m); | |
| function lerpTheta(a, b, t) { | |
| const dt = repeat(b - a, 360); | |
| return lerp(a, a + (dt > 180 ? dt - 360 : dt), t); | |

The updated code is incorrect: amt+(end-start)*amt should be start+(end-start)*amt
How did I miss this?! Thanks so much for catching this.
