Best Practices

• Avoid defining another facet that reads or writes a different slot for pending owner; keep pending-owner state at erc173.owner.pending.
• The current owner in the Two-Step Ownership is stored in the same OwnerStorage as the single-step ownership. Reuse the storage struct to ensure full composability.
