// Package devicecatalog manages the two small reference tables staff pick
|
|
// from when creating an order — device_groups (drives order-number
|
|
// prefixing, see internal/ordernum) and device_brands (a plain name list).
|
|
// Both are owner-curated taxonomy, not order data itself: orders keep their
|
|
// own device_type/device_brand text columns and only optionally link back
|
|
// here via device_group_id/device_brand_id.
