How I read the maker's table
Units printed in each cell ("470 mm", "74,5deg") and decimal commas are dropped or converted. Not published, so null: wheelbase, BB drop, fork offset, trail, standover. Model year not printed (null). An e-gravel bike ("The engine is the Polini EP3 + GP"; "Tera, from whom it inherits the geometries designed for gravel"); "The tire clearance is up to 45 mm". The table also prints CRANK LENGTH (O) per size (not in the schema). Stack and head tube repeat in pairs (S and M 581.6 / 165; L and XL 600.4 / 185), as printed.
