// The plan-switch preview form (spec member-product-discovery; spec
// form-library; design D9, D10, D12). A paid-to-paid switch commits through
// a preview: the target ladder and price ride two hidden fields, the
// proration estimate is prose above them (Binding.Message), and the commit
// is "Confirm switch" beside a "Keep current plan" way out that simply
// re-fetches the plans list, matching the hand-written banner this
// replaces field for field.
//
// This file is the form's home; the registry is only the index (design
// D1). It sits beside member_products.go, which parses through the
// declaration and never through r.FormValue.
