Credit Concentration Top-N / Sector Checker

Screens a flat exposure list (name, sector, amount) for credit concentration: the top-N single-name exposures by amount, a per-sector rollup, single-name and sector Herfindahl-Hirschman Index (HHI, 0–10000 scale), and a breach list against limit percentages you declare. Concentration limits are your own institution's risk-appetite policy, not a fixed regulatory number — nothing is baked in.
