-- RecordGod schema v2.
-- ONE inventory table (vinyl + general goods unified), sales history, slim crates.
-- The Discogs CATALOG is deliberately NOT stored here — it lives in the discogs_full Postgres
-- mirror and is joined on release_id at read time. We keep the shop's OWN data only:
-- WowPlatter crammed a ~3.2M-row Discogs clone into the shop DB; RecordGod keeps ~40k real rows.
