+# ANCHOR:23
+
+---
+
+## 1. Origen de la Marca
+
+Anchor:23 nace de la unión de **dos creativos** con trayectorias distintas y un criterio común: el lujo no es promesa, es estándar.
+
+La marca surge como respuesta a una ausencia clara en la ciudad: un salón que opere bajo reglas de ultra lujo real, con ejecución constante, acceso limitado y una experiencia coherente en cada detalle.
+
+No es una extensión de otra marca. No es una evolución emocional. Es un concepto paralelo, deliberadamente selectivo.
+
+---
+
+## 2. Significado del Nombre
+
+### Anchor
+
+Anchor representa el punto fijo. La base que sostiene y da estabilidad.
+
+En la marca simboliza el estándar bajo el cual se ejecuta cada servicio, decisión y experiencia. No como rigidez, sino como referencia clara.
+
+Es estructura. No ornamento.
+
+### El signo (:)
+
+El signo funciona como una **articulación**.
+
+Ordena el nombre y permite la convivencia de dos criterios creativos dentro de un mismo sistema. No busca significado simbólico ni lectura emocional.
+
+No se explica. No se enfatiza.
+
+Comunica estructura.
+
+### El número 23
+
+El 23 es un **código interno**.
+
+Remite a una idea de dirección, cuidado y constancia entendida de forma cultural y personal, no declarativa. No se presenta como mensaje ni como símbolo explícito.
+
+No se comunica hacia afuera. Opera como fundamento silencioso del concepto.
+
+El cliente no debe entenderlo.
+
+Debe percibirlo en la experiencia: continuidad, calma y seguridad.
+
+---
+
+## 3. Categoría
+
+Belleza de ultra lujo.
+
+Anchor:23 opera como un **concepto exclusivo**, no masivo, con un estándar de servicio que no existe en el mercado local.
+
+---
+
+## 4. Propósito
+
+Ofrecer una experiencia estética exclusiva basada en precisión técnica, coherencia visual y ejecución constante.
+
+---
+
+## 5. Visión
+
+Ser el referente local de belleza ultra exclusiva, reconocido por su nivel de servicio, selección rigurosa y consistencia impecable.
+
+---
+
+## 6. Misión
+
+Operar un concepto de salón de ultra lujo con **una sola sucursal por ciudad**, ajustada al tamaño del mercado, para preservar exclusividad, estándar y coherencia de experiencia.
+
+Anchor:23 no escala por volumen. Escala por selección.
+
+---
+
+## 7. Valores
+
+* Exclusividad — El acceso es limitado por diseño.
+* Excelencia — El estándar es alto y sostenido.
+* Selección — Clientes y equipo cumplen criterios claros.
+* Sobriedad — El lujo se expresa con medida.
+* Consistencia — La experiencia es siempre la misma.
+
+---
+
+## 8. Personalidad de Marca
+
+* Sobria
+* Precisa
+* Selectiva
+* Elegante
+* Reservada
+
+Anchor:23 no busca agradar a todos.
+
+---
+
+## 9. Arquetipo
+
+**El Curador**
+
+Selecciona, eleva estándares y protege la experiencia.
+
+---
+
+## 10. Voz y Tono
+
+### Voz
+
+* Clara
+* Breve
+* Profesional
+
+### Tono
+
+* Seguro
+* Reservado
+* Elegante
+
+Sin adornos. Sin exageraciones.
+
+---
+
+## 11. Identidad Visual
+
+### Principios
+
+* Geometría clara
+* Centro de gravedad estable
+* Amplio espacio negativo
+* Composición silenciosa
+
+Nunca gestual. Nunca decorativa.
+
+---
+
+## 12. Paleta de Color (GitHub Compatible)

+# PRD — AnchorOS
+
+**Codename: Adela**
+
+## 1. Objetivo
+
+AnchorOS es un sistema operativo para salones de belleza orientado a agenda, pagos, membresías e invitados, con reglas estrictas de tiempo, seguridad y automatización.
+
+---
+
+## 2. Principios del Sistema
+
+* UTC-first en todo el backend.
+* UUID como identificador primario interno.
+* Short ID solo para referencia humana.
+* Automatismos auditables.
+* PRD como única fuente de verdad.
+
+---
+
+## 3. Roles y Membresías
+
+### 3.1 Tiers
+
+* Free
+* Gold
+* Black
+* VIP
+
+### 3.2 Tier Gold — Beneficios
+
+* Acceso prioritario a agenda.
+* Beneficios financieros definidos en pricing.
+* Invitaciones semanales.
+
+### 3.3 Ecosistema de Exclusividad (Invitaciones)
+
+* Cada cuenta Tier Gold tiene **5 invitaciones semanales**.
+* Las invitaciones **se resetean cada semana** (Lunes 00:00 UTC).
+* El reseteo es automático mediante:
+
+  * Supabase Edge Function **o**
+  * Cron Job externo.
+* El proceso debe ser:
+
+  * Idempotente.
+  * Auditado en `audit_logs`.
+
+### 3.4 Jerarquía de Roles
+
+* **Admin**: Acceso total. Puede ver PII de clientes y hacer ajustes.
+* **Manager**: Acceso operacional. Puede ver PII de clientes y hacer ajustes.
+* **Staff**: Nivel de coordinación. Puede ver PII de clientes y hacer ajustes.
+* **Artist**: Nivel de ejecución. **Solo puede ver nombre y notas** del cliente. No ve email ni phone.
+* **Kiosk**: Acceso limitado para dispositivos táctiles. No puede acceder a PII de clientes.
+* **Customer**: Nivel más bajo. Solo puede ver sus propios datos.
+
+---
+
+## 4. Gestión de Tiempo y Zonas Horarias
+
+* **Todos los timestamps se almacenan en UTC**.
+* `locations.timezone` define la zona local del salón.
+* Conversión a hora local:
+
+  * Solo en frontend.
+  * Solo en notificaciones (WhatsApp / Email).
+* Backend, reglas de negocio y validaciones **operan exclusivamente en UTC**.
+
+---
+
+## 5. Agenda y Bookings
+
+### 5.1 Identificadores
+
+* Cada booking tiene:
+
+  * `id` (UUID, primario).
+  * `short_id` (6 caracteres alfanuméricos).
+
+### 5.2 Short ID — Reglas
+
+* Se genera antes de persistir el booking.
+* Debe verificarse unicidad.
+* Si existe colisión:
+
+  * Reintentar generación hasta ser único.
+* El Short ID:
+
+  * Es referencia de pago.
+  * Es identificador operativo.
+  * **No sustituye** el UUID.
+
+---
+
+## 6. Pagos
+
+* Stripe como proveedor principal con webhooks para eventos de pago.
+* El Short ID se utiliza como referencia visible para clientes.
+* UUID se mantiene interno para integridad de datos.
+* Lógica de depósitos dinámicos: $200 fijo vs 50% del servicio según timing.
+* Sistema automático de penalizaciones por no-show con posibilidad de waivers.
+* Soporte para múltiples métodos de pago en POS (efectivo, tarjeta, transferencias, giftcards, membresías).
+
+---
+
+## 7. Auditoría
+
+* Toda acción automática o crítica debe registrarse en `audit_logs`.
+* Incluye:
+
+  * Reseteo de invitaciones.
+  * Cambios de estado de bookings.
+  * Eventos de pago.
+
+---
+
+## 8. Límites de los Agentes de IA

-# PRD — AnchorOS
-
-**Codename: Adela**
-
-## 1. Objetivo
-
-AnchorOS es un sistema operativo para salones de belleza orientado a agenda, pagos, membresías e invitados, con reglas estrictas de tiempo, seguridad y automatización.
-
----
-
-## 2. Principios del Sistema
-
-* UTC-first en todo el backend.
-* UUID como identificador primario interno.
-* Short ID solo para referencia humana.
-* Automatismos auditables.
-* PRD como única fuente de verdad.
-
----
-
-## 3. Roles y Membresías
-
-### 3.1 Tiers
-
-* Free
-* Gold
-
-### 3.2 Tier Gold — Beneficios
-
-* Acceso prioritario a agenda.
-* Beneficios financieros definidos en pricing.
-* Invitaciones semanales.
-
-### 3.3 Ecosistema de Exclusividad (Invitaciones)
-
-* Cada cuenta Tier Gold tiene **5 invitaciones semanales**.
-* Las invitaciones **se resetean cada semana** (Lunes 00:00 UTC).
-* El reseteo es automático mediante:
-
-  * Supabase Edge Function **o**
-  * Cron Job externo.
-* El proceso debe ser:
-
-  * Idempotente.
-  * Auditado en `audit_logs`.
-
-### 3.4 Jerarquía de Roles
-
-* **Admin**: Acceso total. Puede ver PII de clientes y hacer ajustes.
-* **Manager**: Acceso operacional. Puede ver PII de clientes y hacer ajustes.
-* **Staff**: Nivel de coordinación. Puede ver PII de clientes y hacer ajustes.
-* **Artist**: Nivel de ejecución. **Solo puede ver nombre y notas** del cliente. No ve email ni phone.
-* **Customer**: Nivel más bajo. Solo puede ver sus propios datos.
-
----
-
-## 4. Gestión de Tiempo y Zonas Horarias
-
-* **Todos los timestamps se almacenan en UTC**.
-* `locations.timezone` define la zona local del salón.
-* Conversión a hora local:
-
-  * Solo en frontend.
-  * Solo en notificaciones (WhatsApp / Email).
-* Backend, reglas de negocio y validaciones **operan exclusivamente en UTC**.
-
----
-
-## 5. Agenda y Bookings
-
-### 5.1 Identificadores
-
-* Cada booking tiene:
-
-  * `id` (UUID, primario).
-  * `short_id` (6 caracteres alfanuméricos).
-
-### 5.2 Short ID — Reglas
-
-* Se genera antes de persistir el booking.
-* Debe verificarse unicidad.
-* Si existe colisión:
-
-  * Reintentar generación hasta ser único.
-* El Short ID:
-
-  * Es referencia de pago.
-  * Es identificador operativo.
-  * **No sustituye** el UUID.
-
----
-
-## 6. Pagos
-
-* Stripe como proveedor principal.
-* El Short ID se utiliza como referencia visible.
-* UUID se mantiene interno.
-
----
-
-## 7. Auditoría
-
-* Toda acción automática o crítica debe registrarse en `audit_logs`.
-* Incluye:
-
-  * Reseteo de invitaciones.
-  * Cambios de estado de bookings.
-  * Eventos de pago.
-
----
-
-## 8. Límites de los Agentes de IA
-
-* Ningún agente puede modificar reglas aquí descritas.
-* Toda implementación debe alinearse estrictamente a este PRD.
-
----
-
-## 9. Estado del Documento
-
-Este PRD es la fuente única de verdad funcional del sistema AnchorOS.
