Enum EngineFlavor 

pub enum EngineFlavor {
    Sheets,
    Excel,
}

Which spreadsheet product’s semantics the engine targets.

The engine flavor also locks the date serial system (P1.4, issue #526):

• Sheets: day 0 = 1899-12-30; no leap-year bug (1900-02-28 = serial 60, 1900-03-01 = serial 61, no serial for the nonexistent 1900-02-29).
• Excel: 1900 date system — serial 1 = 1900-01-01, including the historical Lotus 1-2-3 leap-year bug (serial 60 = the fictitious 1900-02-29). Conversion helpers live in eval::functions::date::serial; Excel evaluation itself is still stubbed (evaluate returns #UNSUPPORTED!).
