cluster-remainder-favors-largest

IN premise

When the budget doesn't divide evenly across clusters, extra slots are distributed one-per-cluster to the largest clusters first via descending size sort.

Summary

Extra capacity that can't be split evenly gets handed out one slot at a time, starting with the biggest clusters. This means larger clusters get a slight additional advantage beyond their proportional share, which could compound over time if cluster sizes are already skewed.
