/**
 * Maps boolean()/enum() columns to the Sheets data validation rules formatSheet()/extendValidation()
 * apply. boolean() columns use ONE_OF_LIST (not the native BOOLEAN checkbox type) deliberately: Sheets'
 * BOOLEAN validation writes a real FALSE into every blank cell it covers, while an unselected ONE_OF_LIST
 * cell stays genuinely empty — see FAQ.md #10 for why that distinction is the actual root cause of the
 * phantom-row issue for boolean() specifically. `defaultBooleanFormat` is the project-wide sheetStyle
 * fallback; a column's own `booleanFormat` (set via `boolean({ format })`) takes priority.
