  CHANGELOG — POS Ferretería Los Villares
  ════════════════════════════════════════════════════════════════════
  v18.031 · 2026-07-30 · printReceipt() ventana principal: @page corregido fuera de @media print.
            Sin popup. Con --kiosk-printing activo imprime sin dialogo.
  v18.029 · 2026-07-30 · Revierte impresión a popup (ventana emergente). cobrar() ya NO
            llama printReceipt() auto; el botón "Imprimir boleta" del modal lo hace.
            Restaura formato correcto del ticket (2 líneas por producto, todo en negro).
  v18.028 · 2026-07-30 · printReceipt() imprime en ventana principal (no popup) para que
            --kiosk-printing de Chrome funcione correctamente. Sin diálogo de impresión.
  v18.027 · 2026-07-30 · Impresión automática: cobrar() llama printReceipt() directo,
            popup se auto-imprime y cierra solo. Agrega 58mm como opción de papel.
  v18.026 · 2026-07-30 · Ticket: línea de detalle qty+precio unitario debajo del nombre.
            Qty=1 solo muestra nombre+total (limpio). Qty>1 muestra "$X c/u ×N  $subtotal".
  v18.025 · 2026-07-29 · Ventas en Espera: botón ⏸ Espera pone el carrito en pausa,
            badge con contador y panel para retomar cualquier venta pausada sin perder nada.
  v18.024 · 2026-07-28 · Devoluciones/Cambios: modal más ancho (960px), botón 👁 en historial
            para ver detalle completo del cambio (tabla con cantidades, precios y subtotales).
  v18.023 · 2026-07-28 · Fix crítico: humanTakeover ahora usa set+merge (antes .update fallaba si
            doc no existe). sendPosMsg pausa bot automático. Bot no dice "Lo siento" ante
            mensajes conversacionales (Dime, Aloooo, etc.) — solo ante búsquedas reales.
  v18.022 · 2026-07-28 · Responder al cliente desde POS y App en modo "Tomar":
            campo de texto + botón Enviar que manda mensaje por WhatsApp API.
            Notificaciones de escritorio al llegar mensajes (POS + App).
  v18.021 · 2026-07-27 · Fix inventario definitivo: Firebase guarda "count" en cada push.
            Al iniciar, si Firebase tiene MAS productos que local, SIEMPRE descarga Firebase.
            Elimina el bug donde el PC del meson subía su caché vieja pisando los productos.
  v18.020 · 2026-07-27 · Botón WhatsApp créditos: ahora abre wa.me desde celular personal
            en vez de webhook n8n. Mensaje pre-llenado con saldo, fecha y artículos.
  v18.019 · 2026-07-27 · Blindaje productos v2: _fbProductsSynced bloquea push automático
            durante sync de inicio. Fix definitivo del bug que revertía productos a 666.
  v18.018 · 2026-07-24 · Protección máxima de datos críticos (LEY): cot_hist y fiados
            nunca se sobreescriben con arrays vacíos ni desde persist() ni desde pull
            automático. Firebase vacío jamás borra datos locales existentes.
  v18.017 · 2026-07-24 · Fix búsqueda POS: al escribir en el buscador muestra hasta 600
            resultados (antes limitado a 120, productos con letra P+ no aparecían).
            En modo browse (sin texto) mantiene los 120 por rendimiento.
  v18.016 · 2026-07-24 · Fix definitivo pérdida de datos: al conectar a Firebase detecta
            si gastos/fiados/cotizaciones/cierres están vacíos en local y los descarga
            automáticamente sin necesidad de presionar Sync. Restaura cot_n automáticamente.
  v18.015 · 2026-07-24 · Fix raíz de pérdida de datos: pull automático al iniciar ahora
            descarga TODOS los datos (gastos, fiados, cotizaciones, cierre caja, órdenes,
            devoluciones) — antes solo bajaba 4 colecciones. Restaura cot_n automáticamente.
  v18.014 · 2026-07-23 · Fix crítico: cotizaciones ahora suben a Firebase inmediatamente
            al guardar y al generar PDF (antes solo se subían al cerrar caja).
            Límite corregido de 30→100 cotizaciones. Fix aplicado también en eliminar.
  v18.013 · 2026-07-23 · Botones: press effect táctil en todos los botones. Emojis
            reemplazados por iconos SVG (Feather style) en botones de pago,
            imprimir, historial, buscar EAN, subir imagen, descuento y devolución.
  v18.012 · 2026-07-23 · Cotizaciones y fiados sincronizados con Firebase. Snapshot de fiados
            y cotizaciones en cada cierre de caja (igual que inventario_snapshot).
            persist() incluye cot_hist. syncTodo() carga cotizaciones desde nube.
  v18.011 · 2026-07-22 · KPI Conversaciones en Dashboard (dona interactiva + detalle por etapa)
  v18.010 · 2026-07-22 · Módulo Conversaciones CRM (WhatsApp bot — lista, chat, etapas, takeover)
  v18.009 · 2026-07-22 · Cierre de caja hace respaldo completo a Firebase + snapshot
            de inventario en ferreteria/inventario_snapshot. syncTodo sincroniza
            productos principales. Fix definitivo: catalog init nunca sobrescribe Firebase.
  v18.008 · 2026-07-22 · Corrección crítica: catálogo embebido nunca sobreescribe Firebase
            al borrar localStorage (CHAPA→CERRADURA; vlr_ts=0 en init de catálogo)
  v18.007 · 2026-07-21 · Pago mixto (Débito + Efectivo) en POS y app móvil
  v18.006 · 2026-07-20 · Botón ✏ en historial para cambiar método de pago
            de una venta. Requiere PIN de administrador (omitido si ya
            hay sesión de admin activa). Actualiza localStorage y Firebase.
  v18.005 · 2026-07-19 · Botón 👁 con detalle expandible de artículos
            en tabla Crédito POS. Botón WA solo icono (sin texto).
            Elimina PDF de fiados. Mensaje WA reorganizado (resumen
            primero, artículos abajo). Phone lookup por nombre si
            no hay customerId. Modal solo aparece sin teléfono.
  v18.004 · 2026-07-19 · Logo WhatsApp neón en botón WA, modal propio
            para ingresar teléfono (reemplaza prompt nativo), nombre
            de negocio configurable (NEGOCIO_NOMBRE) en todos los
            mensajes de crédito.
  v18.003 · 2026-07-19 · Envío de estado de cuenta por WhatsApp:
            botón 📲 WA en cada crédito pendiente, genera PDF del
            estado de cuenta (descarga local) y envía mensaje cordial
            al teléfono del cliente via n8n + Meta API.
  v18.002 · 2026-07-18 · Módulo Devoluciones / Cambios (logística
            inversa): registro C-0001, C-0002..., productos devueltos
            y entregados con búsqueda, ajuste automático de stock,
            cálculo de diferencia, cobro o reintegro con 4 métodos
            de pago, historial con tabla, eliminación con reversión
            de stock. Disponible en APK y POS.
  v18.001 · 2026-07-03 · Tipos de unidad por producto: UN / MT / KG
            / LT. Cantidades decimales (paso 0.5) para MT/KG/LT.
            Unidad visible en grid POS, carrito, historial, inventario
            y tickets impresos.
  v18.000 · base inicial — sistema POS completo con inventario,
            ventas, fiados, cotizaciones, dashboard y sincronización
            Firebase/Firestore.
