{{-- v1.9 — Fase 1E-E6 P1 (regla 6b): filtro #fTipo muestra "Nombre (ABREV)" en lugar de "CODE — name_es". --}}
{{-- v1.8 — Fase 1D (Point 2): badge tipo usa material_type_name + short + color en lugar de mtLabels. --}}
{{-- v1.7 — Fase 1B: fTipo amplía a 7 tipos; mtLabels usa material_type_code/material_type fallback. --}}
{{-- v1.6 — Bug fix: type="search" + autocomplete="new-password"; oninput debounce 300ms desde 2 chars; btnClearProd recarga lista. --}}
{{-- v1.5 — Botón "Volver a Inventario" movido al panel-toolbar del card Seleccionar Producto. --}}
{{-- v1.4 — Layout 5 filas (Producto / Ubicación col-12 4-dropdowns / Lote+Cantidades / Obs / Botones); cascade Rack. --}}
