Frozen Treasure Reverse Analyzer — Target Roses → Minimum Keystones

Given a target rose count, Monte-Carlo compares opening strategies (Open All / Red+Gold / Red Only / Hybrid) and returns the expected keystone cost with confidence intervals.

Box-opening strategies are usually discussed in vibes-based terms, but the expected keystone cost differs measurably by strategy. This calculator runs a Monte-Carlo against the actual drop table, refresh costs, and milestone rewards, and returns the minimum-cost strategy for any target rose count.
