+ *   Line 1: primary label (left, text-sm font-semibold truncate) + amount (right, text-sm font-semibold).
+ *   Line 2: secondary metadata (left, text-xs text-muted-foreground) + optional date (right, text-xs text-muted-foreground).
+ * Pure presentational — parent owns the data.
+ * Props: see FinanceRowProps. */
