Crate mz_row_spine 

Packed-bytes differential dataflow spine Layouts for Row-valued arrangements.

The spines defined here store Row keys and values as concatenated bytes in a single contiguous backing region (via mz_ore::region::Region, which uses lgalloc when available), instead of as separately-allocated heap objects. This gives cursor lookups block locality and lets the OS evict cold pages cleanly under memory pressure.
