placeHandles関数
リファレンスの説明と例は英語です。見出しと目次は日本語です。
Places every handle clear of the ones before it.
Greedy and order-dependent by design: the caller has already sorted the marks into the order they are numbered, and a handle that has found a home does not move to make room for a later one. With a handful of choices on a board that is enough, and it keeps the placement stable as tones change mid-question.

const spots = placeHandles([{ item: "a", centroid: [50, 50] }, { item: "b", centroid: [52, 50] }], 4);
console.log(spots.map((spot) => spot.item).join(" "), Math.hypot(spots[0]!.hx - spots[1]!.hx, spots[0]!.hy - spots[1]!.hy) >= 8);
