/**
 * Abbreviate a number for table cells: `12042` → `"12k"`, `59614283` → `"59.6m"`.
 *
 * Rules (from the Number display & abbreviation guide):
 * - Suffixes: k (10³), m (10⁶), b (10⁹), t (10¹²) — lowercase, no space
 * - Boundary: moves to next suffix when rounding would reach 1000×
 * - Precision: ≥100 → 0 decimals; 10–99 → 1 decimal (drop .0); 1–9.9 → 1 decimal
 * - Negative numbers supported
