── Display ordering ──

Mirrors Field::Base ordering helpers byte-for-byte (per CONTEXT.md inline-duplication decision; see Phase 01 validate_parent_scope_invariant precedent). Keep the two implementations symmetric — when one changes, the other should change in the same commit. See field/base.rb for rationale comments on the partition-level FOR UPDATE locking strategy.
