feat: Implement BLOCKER-001 proactive refresh + E2E video tests (frontend)

BLOCKER-001: Token Refresh Improvements (FASE 4 frontend)
- Proactive refresh scheduler: refresh 5min before token expiry
- Multi-tab synchronization with BroadcastChannel API
- Automatic scheduling on X-Token-Expires-At header reception
- Background token refresh to prevent user interruption

E2E Tests: Video Upload Module (frontend - 62 tests)
- Suite 1: Form tests (27 tests) - 3-step wizard validation
- Suite 2: Service tests (20 tests) - Multipart upload logic
- Suite 3: Integration tests (15 tests) - Complete flow validation

Test infrastructure:
- vitest.config.ts (NEW) - Vitest configuration with jsdom
- src/__tests__/setup.ts (NEW) - Global test setup and mocks
- Updated payments-stripe-elements.test.tsx to use Vitest (vi.mock)

Changes:
- apiClient.ts: Proactive refresh scheduler + BroadcastChannel sync
- payments-stripe-elements.test.tsx: Migrated from Jest to Vitest

Tests created:
- video-upload-form.test.tsx (27 tests) - Component validation
- video-upload-service.test.ts (20 tests) - Service logic validation
- video-upload-integration.test.tsx (15 tests) - Integration flow

Additional documentation:
- Module README.md files for assistant, auth, education, investment, payments, portfolio, trading
- Investment module: Analysis, contracts, gaps, delivery documentation
- Payments module: Stripe integration, wallet specification

+
+// Uso en router
+<Route path="/login" element={<Login />} />
+<Route path="/register" element={<Register />} />
+
+// Uso de store
+function MyComponent() {
+  const { user, isAuthenticated, login, logout } = useAuthStore();
+
+  const handleLogin = async () => {
+    await login('user@example.com', 'password123');
+  };
+
+  return (
+    <div>
+      {isAuthenticated ? (
+        <>
+          <p>Bienvenido, {user?.email}</p>
+          <button onClick={logout}>Cerrar sesión</button>
+        </>
+      ) : (
+        <button onClick={handleLogin}>Iniciar sesión</button>
+      )}
+    </div>
+  );
+}
+```
+

+## RESUMEN EJECUTIVO
+
+### Panorama General
+
+El módulo OQI-004 (Cuentas de Inversión) implementa un sistema completo de gestión de portafolios con 3 productos de inversión (Atlas, Orion, Nova). El 35% está implementado y funcional en producción.
+
+### Componentes Principales
+
+| Componente | Archivos | Líneas | Estado |
+|------------|----------|--------|--------|
+| Páginas (8) | 8 | ~2,000 | ✅ Prod |
+| Componentes (6) | 6 | ~1,500 | ✅ Prod |
+| Total Frontend | 14 | ~3,500 | ✅ Prod |
+
+### Funcionalidades Activas
+

+# OQI-005: Análisis de Gaps - Funcionalidades Faltantes
+
+**Módulo:** OQI-005 (pagos-stripe)
+**Fecha:** 2026-01-25
+**Criticidad:** Las siguientes features no están implementadas pero serían valiosas para UX completa
+
+---
+
+## Gap 1: Refunds UI (Devoluciones)
+
+**Prioridad:** Alta
+**Complejidad:** Media
+**Impacto:** UX, Legal, Soporte
+
+### Descripción del Gap
+
+Actualmente no existe:
+- UI para iniciar devoluciones de pagos
+- Panel de historial de reembolsos procesados
+- Validación de período de devolución (ej: 30 días)
+- Estados de devolución (pending, processing, completed, failed)
+- Notificaciones al usuario cuando devolución se procesa
+
+### Casos de Uso
+
+```
+1. Usuario solicita reembolso de suscripción
+   ├── Verifica si está dentro de período permitido (14 días)
+   ├── Selecciona razón de devolución
+   ├── Backend procesa via Stripe API
+   ├── Estado se actualiza a "pending"
+   └── Usuario notificado cuando se completa (1-3 días)
+
+2. Usuario ve historial de reembolsos
+   ├── Tabla en Billing.tsx → Nueva tab "Reembolsos"
+   ├── Muestra:
+   │   ├── Fecha de solicitud
+   │   ├── Monto reembolsado
+   │   ├── Motivo
+   │   ├── Estado (pending/completed/failed)
+   │   └── Método devolución (mismo método pago original)
+   └── Filtros: status, fecha range
+
+3. Administrador revisa reembolso rechazado
+   ├── Dashboard de admin ver motivo rechazo
+   ├── Opción de re-procesar
+   └── Notificar usuario
+```
+
+### Componentes Necesarios
+
+```typescript
+// 1. RefundRequestModal (modal para solicitar devolución)
+interface RefundRequestModalProps {
+  isOpen: boolean;
+  onClose: () => void;
+  subscriptionId: string;
+  daysRemaining: number;              // Días dentro período permitido
+  refundableAmount: number;
+  onSuccess?: () => void;
+}
+
+// 2. RefundList (tabla historial reembolsos)
+interface RefundListProps {
+  subscriptionId?: string;
+  compact?: boolean;
+  itemsPerPage?: number;
+}
+
+// 3. RefundDetail (modal detalle reembolso)
+interface RefundDetailProps {
+  refundId: string;
+  onClose: () => void;
+}
+```
+
+### Endpoint Backend Requerido
+
+```
+POST /payments/refunds
+├── Body: { subscriptionId, amount, reason, requestedAt }
+├── Valida: Dentro de período permitido (30 días default)
+├── Respuesta: { id, status, amount, reason, processedAt? }
+└── Webhook: refund.completed → Actualizar wallet usuario
+
+GET /payments/refunds
+├── Query params: subscriptionId, status, dateRange
+└── Respuesta: Paginated list
+
+GET /payments/refunds/{id}
+├── Detalle de reembolso
+└── Historial de actualizaciones
+
+DELETE /payments/refunds/{id}
+├── Solo si status=pending
+└── Cancelar devolución pendiente
+```
+
+### Lógica de Negocio
+
+```
+Período Devolución: 14 días desde primera facturación
+├── Free trial: +7 días adicionales
+├── Payment failed: No aplica devolución
+└── Upgrade/downgrade: Proporcional a días usados
+
+Estados:
+├── pending: Enviada a Stripe, sin procesar
+├── processing: Stripe la está procesando
+├── completed: Completada, fondos devueltos
+├── failed: Rechazada por banco/Stripe
+└── cancelled: Usuario canceló solicitud
+
+Reglas:
+├── 1 reembolso/cliente/30 días (máximo)
+├── Monto: hasta 100% de suscripción
+└── Notificación: Email cuando se complete
+```
+
+### Estimación Esfuerzo
+
+- **Backend:** 8-12 horas (Stripe API integration, webhook, DB)
+- **Frontend UI:** 6-8 horas (modal, tabla, detalle)
+- **Testing:** 4-6 horas
+- **Documentación:** 2-3 horas
+- **Total:** ~20-29 horas
+
+---
+
+## Gap 2: Histórico de Cambios de Plan
+
+**Prioridad:** Media
+**Complejidad:** Baja
+**Impacto:** UX, Auditoría, Soporte
+
+### Descripción del Gap
+
+Actualmente no existe:
+- Visualización del historial de cambios de plan
+- Fechas de cambio y razones
+- Comparativa plan anterior vs nuevo
+- Créditos/cargos aplicados en cada cambio
+- Timeline visual de evolución de suscripción
+
+### Casos de Uso
+
+```
+1. Usuario revisa su historial de planes
+   ├── Nueva tab en Billing: "Historial de Planes"
+   ├── Timeline/tabla mostrando:
+   │   ├── Fecha cambio

+### Estimación Esfuerzo
+
+- **Backend:** 4-6 horas (queries, DB si no existe tabla)
+- **Frontend UI:** 4-6 horas (timeline, tabla, modal)
+- **Testing:** 2-3 horas
+- **Documentación:** 1-2 horas
+- **Total:** ~11-17 horas

+
+## Gap 3: Preview de Factura
+
+**Prioridad:** Media
+**Complejidad:** Baja
+**Impacto:** UX, Confianza del Usuario
+
+### Descripción del Gap
+
+Actualmente no existe:
+- Preview de factura ANTES de completar pago
+- Visualización de items que se facturarán
+- Cálculo claro de subtotal, impuestos, descuentos
+- Confirmación de direcciones de facturación
+- Mostrar si hay cambios desde checkout anterior
+
+### Casos de Uso
+
+```

+### Estimación Esfuerzo
+
+- **Backend:** 6-8 horas (cálculo impuestos, endpoints)
+- **Frontend UI:** 4-6 horas (modal, forms, updates)
+- **Tax Integration:** 2-4 horas (si usa servicio externo)
+- **Testing:** 3-4 horas
+- **Documentación:** 1-2 horas
+- **Total:** ~16-24 horas

+---
+
+## Gap 4: Payment Intent Flow (Completo)
+
+**Prioridad:** Alta (Seguridad)
+**Complejidad:** Alta
+**Impacto:** Seguridad, PCI-DSS Compliance
+
+### Descripción del Gap
+
+Actualmente:
+- ✅ Usa Stripe Hosted Checkout (seguro, delegado)
+- ❌ NO implementa Payment Intent flow en cliente
+- ❌ Métodos de pago sin tokenización Stripe.js
+- ❌ NO soporta 3D Secure / SCA en cliente (delegado a backend)
+- ❌ NO maneja tarjetas declinadas gracefully
+
+### Casos de Uso
+
+```
+1. Usuario completa checkout con tarjeta nueva (Hosted Checkout)
+   ├── Redirección a Stripe
+   ├── Stripe maneja validación, 3DS, etc
+   ├── Redirige back a CheckoutSuccess
+   └── ✅ Funciona (implementado)
+
+2. Usuario agrega método de pago desde Billing
+   ├── Abre formulario PaymentMethodForm
+   ├── ❌ Envía número de tarjeta SIN tokenizar
+   ├── Backend debería rechazar (PCI risk)
+   └── Debería usar Stripe.js Elements
+
+3. Usuario paga con saved payment method
+   ├── No aplica (solo checkout con hosted)
+   └── Si se implementa: requiere Payment Intent
+
+4. 3D Secure required
+   ├── Backend detecta SCA required
+   ├── Devuelve clientSecret
+   ├── ❌ Frontend no maneja confirmación
+   ├── Debería usar Stripe.js confirmCardPayment
+   └── Mostrar modal de autenticación
+```
+
+### Componentes Necesarios
+
+```typescript
+// 1. StripeProvider (wrappear app)
+import { Elements } from '@stripe/react-stripe-js';
+import { loadStripe } from '@stripe/js';
+
+const stripePromise = loadStripe(STRIPE_PUBLIC_KEY);
+
+// 2. PaymentMethodForm refactorizado
+interface PaymentMethodFormProps {
+  onSuccess: (paymentMethodId: string) => void;
+  onCancel?: () => void;
+  onError?: (error: string) => void;
+  setAsDefault?: boolean;
+}
+
+// 3. PaymentIntentModal (para confirmar 3DS)
+interface PaymentIntentModalProps {
+  clientSecret: string;
+  onSuccess: () => void;
+  onError: (error: string) => void;
+}
+```
+
+### Cambios Necesarios
+
+```typescript
+// BEFORE (Inseguro)
+const handleSubmit = async (e) => {
+  const result = await addPaymentMethod({
+    type: 'card',
+    card: {
+      number: cardNumber,       // ❌ PCI risk
+      exp_month: expiry.split('/')[0],
+      exp_year: 2000 + parseInt(expiry.split('/')[1]),
+      cvc: cvc,                 // ❌ PCI risk

+    type: 'card',
+    card: cardElement,
+  });
+
+  if (!error) {
+    // Enviar token, no tarjeta
+    const result = await addPaymentMethod(paymentMethod.id);
+  }
+};
+```
+
+### Endpoint Backend Requerido

+
+POST /payments/subscriptions/{id}/confirm-payment
+├── Body: { clientSecret, paymentMethodId }
+├── Si requiere SCA: Procesa autenticación
+├── Respuesta: { success, paymentStatus }
+└── Usado para 3D Secure flow
+```
+
+### Estimación Esfuerzo
+
+- **Backend:** 4-6 horas (validar tokens, SCA handling)
+- **Frontend Stripe.js:** 8-10 horas (Elements, intent confirmation)
+- **Testing (incluye SCA test):** 6-8 horas
+- **Documentación:** 2-3 horas
+- **Total:** ~20-27 horas
+
+---
+
+## Gap 5: Apple Pay / Google Pay
+
+**Prioridad:** Baja
+**Complejidad:** Media
+**Impacto:** UX, Conversión (móvil)
+
+### Descripción del Gap
+
+Actualmente no existe soporte para:
+- Apple Pay (en iOS/macOS)
+- Google Pay (en Android/Chrome)
+- Botones "Pay with X" en checkout
+
+### Estimación Esfuerzo
+
+- **Backend:** 2-4 horas (endpoint validation)
+- **Frontend:** 6-8 horas (Stripe Payment Request Button)
+- **Testing:** 4-6 horas (necesita dispositivos)
+- **Total:** ~12-18 horas
+
+---
+
+## Gap 6: Retry Logic para Pagos Fallidos
+
+**Prioridad:** Media
+**Complejidad:** Media
+**Impacto:** Retención, Ingresos
+
+### Descripción del Gap
+
+Actualmente:
+- ❌ No hay reintentos automáticos de pagos fallidos
+- ❌ No hay notificación al usuario cuando falla
+- ❌ No hay UI para re-procesar pago manual
+- ❌ No hay webhook handling para payment_intent.payment_failed
+
+### Casos de Uso
+
+```
+1. Suscripción tiene status "past_due"
+   ├── Payment falló (tarjeta rechazada, fondos insuficientes)
+   ├── Sistema envía email al usuario
+   ├── Usuario puede ver deuda pendiente en Billing
+   ├── Usuario puede:
+   │   ├── Actualizar método de pago
+   │   └── Click "Reintentar pago"
+   └── Stripe reintenta automáticamente (3 veces en 3 días)
+
+2. Dashboard muestra estado "Pago Pendiente"
+   ├── Badge rojo en SubscriptionCard
+   ├── Info: "Tenemos un problema con tu pago"
+   ├── Botones:
+   │   ├── Actualizar método de pago
+   │   └── Reintentar ahora
+   └── Link a portal Stripe
+```
+
+### Endpoints Requeridos
+
+```
+POST /payments/subscription/{id}/retry-payment
+├── Reintenta el pago pendiente
+├── Requiere valid payment method
+└── Respuesta: { success, newStatus, nextRetryDate? }
+
+GET /payments/failed-payments
+├── Listar pagos fallidos del usuario
+└── Respuesta: Array de intentos fallidos con razones
+```
+
+### Estimación Esfuerzo
+
+- **Backend:** 4-6 horas (retry logic, webhooks)
+- **Frontend:** 3-4 horas (UI, forms)
+- **Testing:** 2-3 horas
+- **Total:** ~9-13 horas
+
+---
+
+## Priorización Recomendada
+
+### Fase 1 (MVP - 2-3 semanas)
+1. **Preview de Factura** (16-24 hrs) - Mejor UX antes de pagar
+2. **Retry Logic** (9-13 hrs) - Aumenta retención
+
+### Fase 2 (3-4 semanas)
+3. **Refunds UI** (20-29 hrs) - Cumplimiento legal, UX completa
+4. **Histórico Cambios Plan** (11-17 hrs) - Soporte + auditoría
+
+### Fase 3 (2-3 semanas)
+5. **Payment Intent Flow** (20-27 hrs) - Seguridad PCI-DSS
+6. **Apple Pay / Google Pay** (12-18 hrs) - Conversión móvil
+
+---
+
+## Impacto de No Implementar
+
+| Gap | Riesgo | Impacto |
+|-----|--------|--------|
+| Refunds | Legal/Cumplimiento | Posibles multas/disputas |
+| Historial Cambios | Soporte | Tickets más complejos |
+| Preview Factura | UX | Menor confianza en checkout |
+| Payment Intent | Seguridad | PCI-DSS non-compliant |
+| Apple/Google Pay | Conversión | Pérdida clientes móviles |
+| Retry Logic | Ingresos | Pérdida 5-10% suscriptores |

+# OQI-005: Integración Stripe - Análisis Técnico
+
+**Módulo:** OQI-005 (pagos-stripe)
+**Enfoque:** Frontend Stripe integration, flujos de checkout, métodos de pago
+**Fecha:** 2026-01-25
+
+---
+
+## 1. Integración Stripe - Visión General
+
+### Estado Actual
+- ✅ **Checkout Modal:** Stripe Hosted Checkout (redirect)
+- ✅ **Métodos de Pago:** Gestión tarjetas via API backend
+- ✅ **Webhooks:** Procesados en backend (no visible en frontend)
+- ⚠️ **Stripe.js Elements:** NO implementado (formulario manual sin tokenización)
+- ⚠️ **3D Secure / SCA:** Delegado a backend/Stripe
+
+### Flujo de Pago Principal
+
+```
+Usuario selecciona plan
+    ↓
+Pricing.tsx → handleSelectPlan()
+    ↓
+payment.service.createCheckoutSession(planId, interval)
+    ↓
+POST /payments/checkout → Backend crea Stripe Session
+    ↓
+Respuesta: { sessionId, url }
+    ↓
+window.location.href = url (redirige a Stripe Hosted Checkout)
+    ↓
+Usuario completa pago en Stripe
+    ↓
+Stripe redirige a CheckoutSuccess page con session_id param
+    ↓
+CheckoutSuccess espera 2s y llama fetchCurrentSubscription()
+    ↓
+Dashboard actualizado con nueva suscripción
+```
+
+---
+
+## 2. Flujos de Checkout Implementados
+
+### 2.1 Checkout Sesión (Subscripción)
+
+**Página:** `Pricing.tsx`
+
+```typescript
+const handleSelectPlan = async (planId: string, selectedInterval: PlanInterval) => {
+  try {
+    const checkoutUrl = await createCheckoutSession(planId, selectedInterval);
+    window.location.href = checkoutUrl;  // Stripe Hosted Checkout
+  } catch (error) {
+    console.error('Error creating checkout session:', error);
+  }
+};
+```
+
+**Endpoint Backend:**
+- `POST /payments/checkout`
+- **Params:** `{ planId, billingCycle (monthly/yearly), successUrl, cancelUrl }`
+- **Response:** `{ sessionId, url }`
+
+**Flujo:**
+1. Obtiene lista de planes desde store
+2. Filtra planes activos
+3. Ordena por precio
+4. Renderiza 4 tarjetas (grid responsivo)
+5. Al hacer click → crea sesión checkout
+6. Redirige a Stripe Hosted Checkout
+
+**Características:**
+- Toggle mensual/anual con visualización de descuento
+- Badge "Más Popular" en plan principal
+- Badge "Plan Actual" si ya tiene suscripción
+- Cálculo mensual equivalente (price/12 para anual)
+- Tabla comparativa características
+- FAQ preguntas frecuentes
+
+### 2.2 Cambio de Plan (Upgrade/Downgrade)
+
+**Componente:** `SubscriptionUpgradeFlow.tsx`
+
+**Flujo 3 Pasos:**
+
+```
+PASO 1: Seleccionar Plan
+├── Lista planes activos
+├── Muestra precio y 4 características
+├── Indica si es Upgrade/Downgrade
+└── Click → Fetch preview
+
+PASO 2: Previsualizar Cambios
+├── Comparación plan actual vs nuevo
+├── Cálculo prorrateo (si upgrade → inmediato, si downgrade → fin período)
+├── Resumen financiero:
+│   ├── Crédito prorrateo (si aplica)
+│   ├── Precio nuevo plan
+│   └── Monto total a pagar/acreditar
+├── Fecha efectiva
+└── Botón confirmar
+
+PASO 3: Éxito
+├── Confirmación visual
+├── Nombre plan nuevo
+└── Botón cerrar
+```
+
+**Endpoint Backend:**
+- `POST /payments/subscription/change-plan`
+- **Params:** `{ planId, billingCycle }`
+- **Response:** `{ id, status, amount, currentPeriodEnd, ... }`
+
+**Nota:** Preview es MOCK en frontend (no implementado en backend)
+
+```typescript
+export async function previewSubscriptionChange(
+  planId: string,
+  interval: PlanInterval,
+  couponCode?: string
+): Promise<SubscriptionPreview> {
+  // Returns hardcoded mock - needs backend implementation
+  return {
+    subtotal: 0,
+    discount: 0,
+    tax: 0,
+    total: 0,
+    currency: 'USD',
+    interval,
+  };
+}
+```
+
+### 2.3 Cancelación de Suscripción
+
+**Página:** `Billing.tsx` → Tab "Resumen"
+
+**Endpoint Backend:**
+- `POST /payments/subscription/cancel`
+- **Params:** `{ immediately: boolean }`
+- **Response:** `{ id, status: 'canceled', canceledAt, ... }`
+
+**Comportamiento:**
+- Por defecto `immediately = false` (cancela al final del período)
+- UI muestra aviso: "Tu suscripción se cancelará el [fecha]"
+- Opción "Reactivar" disponible antes de la fecha de cancelación
+
+**Endpoint Backend (Reactivar):**
+- `POST /payments/subscription/resume`
+- **Response:** `{ id, status: 'active', ... }`
+
+---
+
+## 3. Métodos de Pago
+
+### 3.1 Agregar Método de Pago
+
+**Componente:** `PaymentMethodForm.tsx`
+
+**Flujo:**
+```
+Formulario Manual (sin Stripe.js)
+├── Card Number (validación Luhn, detección brand)
+├── Cardholder Name
+├── Expiry (MM/YY)
+├── CVC (3-4 dígitos)
+└── Checkbox "Set as Default"
+
+Click "Add Card"
+    ↓
+Validaciones locales:
+  ├── Nombre no vacío
+  ├── Número 13-19 dígitos
+  ├── Fecha válida (MM 1-12, no expirada)
+  └── CVC 3-4 dígitos
+    ↓
+POST /payments/methods
+    ↓
+Response: { id, brand, last4, expiryMonth, expiryYear, isDefault }
+```
+
+**Problemas de Seguridad:**
+- ⚠️ **NO usa Stripe.js Elements** - tarjeta se envía al backend en texto plano (NO compliant PCI DSS en frontend)
+- ✅ Debería usar: `@stripe/react-stripe-js` con `CardElement`
+- ✅ Token debe generarse en frontend y pasarse al backend
+
+**Validaciones Locales:**
+```typescript
+const formatCardNumber = (value: string) => {
+  const v = value.replace(/\s+/g, '').replace(/[^0-9]/gi, '');
+  const matches = v.match(/\d{4,16}/g);
+  const match = (matches && matches[0]) || '';
+  const parts = [];
+  for (let i = 0, len = match.length; i < len; i += 4) {
+    parts.push(match.substring(i, i + 4));
+  }
+  return parts.length ? parts.join(' ') : value;
+};
+
+const getCardType = (number: string): string => {
+  const cleanNumber = number.replace(/\s/g, '');
+  if (/^4/.test(cleanNumber)) return 'Visa';
+  if (/^5[1-5]/.test(cleanNumber)) return 'Mastercard';
+  if (/^3[47]/.test(cleanNumber)) return 'Amex';
+  if (/^6(?:011|5)/.test(cleanNumber)) return 'Discover';
+  return 'Card';
+};
+```
+
+### 3.2 Gestionar Métodos de Pago
+
+**Componente:** `PaymentMethodsList.tsx`
+
+**Funcionalidades:**
+- Listar métodos guardados (brand + last4)
+- Badge "Default" si es método predeterminado
+- Alerta si vence en 3 meses
+- Alerta si ya está expirado (desactivado)
+- Menú dropdown (Set as Default, Remove)
+- Modal de confirmación antes de eliminar
+
+**Endpoints:**
+| Acción | Método | Endpoint |
+|--------|--------|----------|
+| Listar | GET | `/payments/methods` |
+| Agregar | POST | `/payments/methods` |
+| Establecer Default | POST | `/payments/methods/default` |
+| Eliminar | DELETE | `/payments/methods/{id}` |
+
+**Lógica Expiración:**
+```typescript
+const isExpiringSoon = (expMonth: number, expYear: number) => {
+  const now = new Date();
+  const expDate = new Date(expYear, expMonth - 1);
+  const threeMonths = new Date();
+  threeMonths.setMonth(threeMonths.getMonth() + 3);
+  return expDate <= threeMonths && expDate >= now;
+};
+
+const isExpired = (expMonth: number, expYear: number) => {
+  const now = new Date();
+  const expDate = new Date(expYear, expMonth);
+  return expDate < now;
+};
+```
+
+### 3.3 Portal de Stripe
+
+**Implementación:** `Billing.tsx` → Botón "Portal de Stripe"
+
+**Endpoint Backend:**
+- `POST /payments/billing-portal`
+- **Params:** `{ returnUrl }`
+- **Response:** `{ url }`
+
+**Uso:**
+```typescript
+const handleOpenBillingPortal = async () => {
+  try {
+    const { url } = await createPortalSession(returnUrl);
+    window.location.href = url;
+  } catch (error) {
+    console.error('Error opening portal:', error);
+  }
+};
+```
+
+**Funcionalidades en Portal (delegadas a Stripe):**
+- Cambiar método de pago predeterminado
+- Actualizar información de facturación
+- Cambiar plan
+- Cancelar/reactivar suscripción
+- Descargar facturas
+- Ver historial de pagos
+
+---
+
+## 4. Flujos Post-Checkout
+
+### 4.1 Checkout Success
+
+**Página:** `CheckoutSuccess.tsx`
+
+```
+URL: /checkout/success?session_id=cs_...
+
+Renderiza:
+├── Loading (2 segundos - espera webhooks Stripe)
+├── Entonces:
+│   ├── CheckCircle icon (verde)
+│   ├── "Pago Exitoso"
+│   ├── Detalles suscripción:
+│   │   ├── Plan name
+│   │   ├── Ciclo (mensual/anual)
+│   │   ├── Estado (Activo)
+│   │   └── Próxima factura
+│   └── Botones:
+│       ├── Ir al Dashboard
+│       └── Ver Detalles de Facturación
+└── Session ID visible (debug)
+```
+
+**Lógica:**
+```typescript
+useEffect(() => {
+  const timer = setTimeout(async () => {
+    try {
+      await fetchCurrentSubscription();  // Refresca desde backend
+    } catch (error) {
+      console.error('Error fetching subscription:', error);
+    } finally {

+## 8. Seguridad - Notas Críticas
+
+### Cumplimiento PCI DSS
+| Item | Estado | Nota |
+|------|--------|------|
+| Tokenización Stripe | ⚠️ Parcial | Backend maneja, frontend envía números en texto |
+| Stripe.js Elements | ❌ No | Necesario para compliant |
+| 3D Secure / SCA | ✅ Backend | Manejado por Stripe + backend |
+| HTTPS | ✅ Asumido | URL origen es HTTPS |
+| Input Validation | ✅ Parcial | Cliente-side Luhn check presente |
+| Rate Limiting | ❌ Desconocido | Debe estar en backend |
+
+### Recomendaciones
+1. **Implementar Stripe.js Elements** para PaymentMethodForm
+2. **Usar Payment Intent API** con confirmación cliente
+3. **Validar CSRF tokens** en todos los POST
+4. **Implementar retry logic** en checkouts fallidos
+5. **Auditar logs** de transacciones en backend
