commerce/api/currency/handlers.go

// Package currency is the HTTP surface for the currency reference table: admin
// CRUD (generic REST) plus a public GET list. Currencies are a GLOBAL reference
// (default namespace, like token/user/organization) — one shared set the
// store/settings and product/price pickers read, replacing a hardcoded array.
//
// Two audiences:
//   - PUBLIC read: GET /v1/commerce/currencies returns the whole list, no auth
//     (it is presentation/reference data). Wired on the commerce public group.
//   - ADMIN write: create/update/delete mutate the reference set and are gated by
//     the /v1 bundle's adminRequired. Wired in api/api.go.
