arrayTernarySpreadingConsistency
Reports inconsistent types when spreading a ternary in an array literal.
✅ This rule is included in the tsstylisticandstylisticStrictpresets.
When spreading a ternary expression in an array literal, prefer using consistent types for both branches. Mixing arrays with empty strings as fallbacks reduces code clarity.
