+# Hotel Front-Office System Design
+
+**Date**: 2026-02-15
+**Status**: Approved
+**Approach**: Module-by-module sequential build (Approach A)
+
+## Decisions
+
+| Decision | Choice |
+|---|---|
+| Scope | All front-office modules |
+| UI Style | Dark theme with gold accents (#d4a574) |
+| Bookings | Channel manager ready (data model supports it, APIs deferred) |
+| Multi-tenant | Deferred - single-hotel system first |
+| Auth | Upgrade to JWT with route protection |
+| Language | Bilingual Spanish/English (react-i18next) |
+
+## Build Order
+
+1. Foundation (JWT, i18n, dark theme, DB schema)
+2. Room Dashboard & Status Management
+3. Reservations Module
+4. Guest Management
+5. Housekeeping
+6. Room Service
+7. Events & Venues
+8. Employee Scheduling
+9. Reports & Analytics
+
+---
+
+## 1. Foundation Layer
+
+### 1.1 JWT Authentication
+
+- Add `jsonwebtoken` and `bcryptjs` packages to backend
+- Create `authMiddleware.js` verifying JWT on all `/api/*` routes except `/api/auth/login` and `/api/auth/refresh`
+- Access token: 15min expiry, stored in memory (frontend)
+- Refresh token: 7 days, httpOnly cookie
+- `POST /api/auth/refresh` endpoint
+- Frontend Axios interceptor: attach token, auto-refresh on 401
+- Update `AuthContext` for token lifecycle
+- DB: `refresh_tokens` table (token, user_id, expires_at, revoked)
+
+### 1.2 Internationalization
+
+- Packages: `react-i18next`, `i18next`, `i18next-browser-languagedetector`
+- Locale files: `/frontend/src/locales/es.json`, `/frontend/src/locales/en.json`
+- Replace `LenguageContext` with i18next provider
+- Language switcher component in navbar
+- New modules use translation keys from start
+- Existing modules migrated incrementally
+
+### 1.3 Dark Theme Design System
+
+CSS custom properties in `theme.css`:
+- Background: `#0a0a0a` (main), `#1a1a1a` (cards), `#2a2a2a` (elevated)
+- Accent: `#d4a574` (gold) for primary actions
+- Text: `#ffffff` (primary), `#a0a0a0` (secondary)
+- Status: green (available), blue (occupied), yellow (cleaning), red (maintenance)
+- Success: `#22c55e`, Warning: `#eab308`, Error: `#ef4444`, Info: `#3b82f6`
+- All new components built with these tokens via Tailwind
+
+### 1.4 Database Schema

+
+## 2. Room Dashboard & Status Management
+
+### API Endpoints
+- `GET /api/rooms/status` - All rooms with current status, guest info, floor
+- `PUT /api/rooms/:id/status` - Update room status (cascading side effects)
+- `GET /api/dashboard/kpis` - Occupancy %, available count, check-ins, check-outs, revenue (today)
+- `GET /api/dashboard/weekly-revenue` - Last 7 days revenue data
+
+### UI Components
+- `RoomDashboard.jsx` - Main page with KPI bar and floor grid
+- `RoomGrid.jsx` - Color-coded room cards organized by floor
+- `RoomDetailModal.jsx` - Room detail popup (guest, amenities, reservation)
+- `KPIBar.jsx` - Top bar with 4-5 metric cards
+- `WeeklyRevenueChart.jsx` - Bar chart component
+- `ArrivalsDepaturesList.jsx` - Today's arrivals/departures
+
+### Business Logic
+- Room status cascade: check-out -> "cleaning", housekeeping done -> "available", check-in -> "occupied"
+- KPIs calculated from rooms and reservations tables
+- Floor data derived from room properties
+
+---
+
+## 3. Reservations Module
+
+### API Endpoints
+- `GET /api/reservations` - List with filters (status, dates, search)
+- `POST /api/reservations` - Create (validates room availability)

+
+### State Machine
+```
+pending -> confirmed -> checked_in -> checked_out
+pending -> cancelled
+confirmed -> cancelled
+```
+
+### Business Rules
+- No double-booking (check availability before creating)
+- Check-in: updates room status to "occupied", creates guest_stay record
+- Check-out: updates room status to "cleaning", creates housekeeping task, closes guest_stay
+- Channel field: direct, booking, expedia, airbnb, other (for future integration)
+
+---
+
+## 4. Guest Management
