{{-- v1.9 — Versión bump confirmación: fix reset() en openGroupModal ya aplicado en v1.8. --}}
{{-- v1.8 — BUG FIX: openGroupModal() llamaba reset() DESPUÉS de set #group_type → type quedaba '' → validación 422 silenciosa. --}}
{{-- v1.7 — Alta de Línea de Producto inline desde modal de Nueva Marca (secondary modal, AJAX POST). --}}
{{-- v1.6 — uppercase-input aplicado en campos de nombre: grupos, marcas, categorías, bundles. Elimina oninput inline de marca. --}}
{{-- v1.5 — FIX: editCategory AJAX URL faltaba prefijo /products → retornaba 404 en silencio. + error callback. --}}
{{-- v1.4 — Grid de marcas vacío al abrir modal nuevo; editar muestra solo marcas asignadas hasta seleccionar industria --}}
{{-- v1.3 — Filtro de industria en modal de grupos: dropdown + renderBrandsGrid() + filterBrandsByIndustry() --}}
{{-- v1.2 — Botones con tooltips y labels. Botón Categories en nuevas pestañas. Fix DELETE POST spoofing. --}}
