/**
 * Interaction penalty when critical AND high findings coexist.
 * Represents compounding risk from multiple severe issue types.
 *
 * Uses min(critical, high) as the bottleneck factor — the penalty scales
 * with the SMALLER of the two counts, preventing a single outlier category
 * from dominating the score. The logarithmic curve ensures diminishing
 * returns, and the result is capped at 10 points maximum.
 *
 * Examples: 3 critical + 2 high → min(3,2)=2 → 5·log₂(3) ≈ 7.9
 *           1 critical + 5 high → min(1,5)=1 → 5·log₂(2) = 5.0
