Constant KIND_LOCAL 

pub const KIND_LOCAL: u8 = 0x01;

Cell kind tags — first byte of every cell’s body after the length prefix. Readers dispatch on this to produce one of:

• a local Cell (this module) — a full row on a leaf page
• an OverflowRef (in the sibling overflow module) — a pointer to a spilled cell body on a leaf page
• an InteriorCell (in interior_page) — a divider on an interior tree node pointing at a child page
