375 suffixes (S 21 / A 81 / B 224 / C 46 / D 3). Value = 0.40×usage (Tranco + Radar) + 0.20×head quality + 0.40×scale. Tiers: S (≥65) / A (≥50) / B (≥30) / C. Risk is a separate axis and does not enter the score.
Inclusion rule: non-Latin suffixes excluded (79 IDNs); all S-tier kept, everything else only if the suffix is ≤4 letters. Original candidate pool: 731. The list shows the top 100 by default.
