-- Durable, administrator-managed regular Star Gift catalog. The previous seven-item
-- animated_emoji-derived directory was development-only and is intentionally not migrated.
-- Existing received rows refer to those non-durable definitions, so clear them instead of
-- manufacturing a read-time compatibility fallback that could no longer reconstruct assets.
