/**
 * Cesta de Intercambio — Página pública /cesta-de-intercambio/
 * Versión: 1.3.0
 *
 * Reutiliza variables de --ltn-*. No usa #hex ni rgba literales.
 * Clases: .ltn-exchange-cart-page-*
 *
 * v1.3.0: "Enviar todo" (Pieza 2, ampliación) pasa a ser el único punto de
 *         entrada para proponer intercambio — se retira el CTA de
 *         "Proponer intercambio" por vendedor de .ltn-exchange-cart-vendor__foot
 *         (que ahora solo puede contener "Completar compra"). Nueva clase
 *         .ltn-exchange-cart-page__foot para el botón "Enviar todo" al pie
 *         de la página, debajo de todos los bloques de vendedor.
 * v1.2.0: Vista híbrida compra+intercambio por proveedor.
 *         Nuevas clases: .ltn-exchange-cart-subsection, .ltn-exchange-cart-subsection--purchase,
 *         .ltn-exchange-cart-item--purchase, .ltn-exchange-cart-purchase-subtotal,
 *         .ltn-exchange-cart-overlap-notice.
 * v1.1.0: Fix scroll modal #ltn-exchange-confirm-modal (sin barra visible,
 *         sin desborde horizontal); bloqueo auto-intercambio en UI (.trade-orb--own).
