Card grants produce a post-state-total entry and run the CardCosmeticReward
cascade (foil twin → id-1 lookup). Cascade additions are skipped when the
viewer already owns the cosmetic; missing-master-row failures are logged
and dropped without failing the parent grant.

Sleeve/Emblem/Skin/Degree/MyPageBG grants are idempotent on the viewer's
owned-collection but always emit a wire entry at the top level (preserves
"+1 sleeve" purchase popup). Unknown ids throw InventoryCatalogException.

Crystal/Rupy/RedEther/SpotCardPoint grants mutate ViewerCurrency in place
and emit post-state-total wire entries. Op log records the post-state for
later currency-collision resolution in CommitAsync.

mutation methods throw NotImplementedException until subsequent tasks
land them.
