// Package orders lets a customer place an order directly from the
// storefront, and lets the admin track and update it. Pricing is never
// trusted from the client: each line is resolved against the pricing
// module's authoritative price tier at creation time.
//
// Whether an order requires a logged-in (and possibly identity-verified)
// customer account is an admin-configurable gate, not a fixed rule of this
// package -- see gate.go and site.Settings.CustomerAccountsEnabled.
