{{-- v3.5 — Recepción R1 (Puntos 1.2 y 2.5, hallazgos V1/V3 de VB-4): Tab 1 reemplaza los 3 campos
         libres de documento (supplier_document/bill_of_lading/supplier_invoice, ninguno se
         persistía) por un selector de tipo de documento (catálogo) + un solo folio + motivo (solo
         visible con tipo "Sin Documento"). onZoneChange() reemplaza autoAssignBin()/checkTab1()
         (no-op) para el bin: al elegir/cambiar de zona, consulta al servidor (suggest-bin) con el
         warehouse_id/zone_id REALES del formulario — antes, autoAssignBin() asignaba el bin
         sugerido por searchPo() contra el almacén POR DEFECTO del sistema, sin importar cuál
         eligiera el operador en el selector; si eran distintos, el bin quedaba mal asignado. Si no
         hay bin libre en la zona, se muestra el error y se bloquea "Siguiente". checkDocumentFolio()
         avisa (sin bloquear salvo folio duplicado en tipo único) contra check-document al salir del
         campo de folio.
--}}
{{-- v3.4 — Fase 1E-E6 P1 (regla 6b): buildPoItemsStrip() y showProductModal() mostraban material_type_code
         solo (con fallback silencioso a 'TR') — searchPo() ahora manda material_type_name/short/color
         (WarehouseReceptionController v4.4) y ambas funciones arman "Nombre (ABREV)". --}}
{{-- v3.3 — Fase 1D (Point 2): badge tipo usa material_type_name + short + color en lugar de bg-secondary+code. --}}
{{-- v3.2 — Fase 1B: JS usa material_type_id (int) como llave de suggestedBins; no_bins_message desde servidor.
             buildRulesTab muestra "No aplica" cuando rules=[]. buildItemsTab usa material_type_code. --}}
{{-- v3.1 — novalidate en <form>: fix silent-block en formularios multi-tab con required. --}}
{{-- v2.1 — buildRulesTab: pre-llena Expected desde datos OC. Auto-match con tolerancia. --}}
{{-- v2.0 — Wizard 4 tabs SAP-style: Document -> Verification -> Items -> Confirm.      --}}
{{-- v3.0 — PO Info Strip muestra items con part#, SKU, material type y bin sugerido.   --}}
{{--         Modal de detalle de producto. searchPo retorna suggested_bins.              --}}
