pub const FORMAT_VERSION: u16 = _; // 1u16Expand description
Version a newly created store is stamped with. The compact-cells cargo
feature still decides only this default; opening never restamps it.
NOT the disk-format stamp. crate::FORMAT_VERSION (page bytes 18-19) is
the sekejap disk format of the FILE and is always 2; this one is the
logical superblock version of the inherited kernel Store and says what
its pages contain.
