// Package currency is the currency entity domain: the reference table of the

// currencies a store accepts, addressable by ISO-4217 Code. It is a global
|
|
// (default-namespace) reference set — the single source the store/settings and
|
|
// product/price currency pickers read, replacing a hardcoded array. The bare
|
|
// value type (usd/eur/…) and its symbol/decimal conventions still live in
|
|
// models/types/currency; this entity carries the editable, seedable rows.
