// The group-mapping form (spec discourse-operator-surface "Entitlement-to-
// group mapping management"; spec form-library; design D2, D12; finding
// FA-8). A dense sub-record form, like every other add-a-row panel on the
// operator surface: the entitlement select opens with a disabled, selected
// "Choose an entitlement" placeholder, so the browser cannot preselect a
// resource key the operator never chose, and a submission whose entitlement
// is not one of the offered options is refused rather than resolved to a
// default.
//
// This file is the form's home; the registry is only the index (design
// D1). It sits beside operator.go, which parses through the declaration
// and never through r.FormValue. The integration imports internal/forms
// directly and registers through the same forms.Register every console
// form uses.
