/**
 * /mi-cesta/ como una factura — Página pública /mi-cesta/
 * Versión: 1.1.0
 *
 * Compra de cada vendedor como una factura (líneas, envío, base imponible,
 * IVA y total), recuadro de intercambio que no suma (DEUDA-DASHBOARD-044) y
 * resumen general con dos o más vendedores (F2c-ter, PLAN-MI-CESTA-FACTURA,
 * allage-dashboard 2.80.0; base imponible desde 2.80.1). Plantilla:
 * modules/allage-dashboard/templates/public/exchange-cart-page.php.
 *
 * Clases: .ltn-cesta*, .ltn-invoice*, .ltn-invoice-line*,
 * .ltn-invoice-totals, .ltn-invoice-exchange*, .ltn-cesta-summary*.
 * Solo variables --ltn-* (shared/variables.css). Reutiliza .ltn-button
 * (shared/buttons.css), .ltn-qty-stepper y .ltn-cart-item__remove
 * (shared/cart-page.css), .ltn-alert (shared/alerts.css) y el estado vacío
 * .ltn-exchange-cart-empty (shared/exchange-cart-page.css).
 *
 * El resumen general no es sticky: el overflow-x: hidden de html y body del
 * tema (header.css, que /mi-cesta/ carga con wp_head()) lo rompe
 * (DEUDA-CSS-007).
