This game compares published plant trait rows from EOL TraitBank.

• Each plant uses a single comparable trait value or ordered class drawn from the underlying source rows.
• Binary rounds ask which plant scores higher on that one trait, not which one is broadly more successful.
• Trait rows can come from USDA Plants, FAO EcoCrop, or TRY-backed EOL records depending on the metric.

This is a tolerance window, not a favorite single pH.
