+# EMS Frontend Template Development Guidelines
+
+## Overview
+EMS Frontend Template is the shared base UI framework for all EMS customer projects. Customer repos (tianpu-ems, zpark-ems, etc.) fork or copy from this template and customize for their specific deployment.
+
+## Golden Rules
+- This is a TEMPLATE repo -- changes here must be propagated to customer repos manually
+- Use i18n for ALL user-visible strings (`src/i18n/zh.json` + `en.json`), never hardcode Chinese or English text
+- Theme customization goes through ThemeContext (`src/contexts/ThemeContext.tsx`)
+- All API calls go through `src/services/api.ts` -- never use raw axios/fetch in page components
+- Feature flags control page visibility via `/api/v1/branding` endpoint
+- Follow Conventional Commits: `<type>(<scope>): <description>`
+- Types: feat, fix, refactor, docs, test, chore, style, perf
+
+## Tech Stack
+- React 19 + TypeScript
+- Ant Design 5 + ProComponents
+- ECharts 6 (charts and dashboards)
+- Three.js + React Three Fiber (optional 3D visualization)
+- i18next (zh + en localization)
+- Vite 8 (build tool)
+- Axios (HTTP client)
+
+## Architecture
+```
+src/
+  pages/           # Page components (one folder per feature)
+  layouts/         # Layout components (MainLayout with sidebar)
+  contexts/        # React contexts (ThemeContext for branding)
+  hooks/           # Custom hooks (useRealtimeWebSocket, etc.)
+  services/        # API service layer (api.ts is the single entry point)
+  i18n/            # Internationalization files (zh.json, en.json)
+  utils/           # Utility functions
+  assets/          # Static assets (images, fonts)
+  App.tsx          # Root component with route definitions
+  main.tsx         # Entry point
+```
+
+## Page Structure
+- `Dashboard/` -- Main overview dashboard
+- `Monitoring/` -- Real-time device monitoring
+- `Devices/` + `DeviceDetail/` -- Device management and detail views
+- `Analysis/` -- Energy analysis (cost, loss, YoY, MoM)
+- `Alarms/` -- Alarm center
+- `Carbon/` -- Carbon emissions tracking
+- `Reports/` -- Report center
+- `BigScreen/` + `BigScreen3D/` -- 2D and 3D visualization screens
+- `Charging/` -- EV charging management
+- `Prediction/` -- Energy prediction
+- `EnergyStrategy/` -- Energy strategy optimization
+- `AIOperations/` -- AI-assisted operations
+- `Maintenance/` -- Maintenance management
+- `DataQuery/` -- Data query interface
+- `Management/` -- General management
+- `Quota/` -- Energy quota
+- `System/` -- System settings and audit log
+- `Login/` -- Login page
+
+## How to Customize for a New Customer
+1. Copy this template into the new customer repo's `frontend/` directory
+2. Update `src/contexts/ThemeContext.tsx` -- branding colors, customer name
+3. Update `src/layouts/MainLayout.tsx` -- logo, sidebar menu items
+4. Edit `src/App.tsx` -- add/remove routes per customer needs
+5. Update `vite.config.ts` -- adjust proxy target if backend port differs
+6. Remove unused dependencies from `package.json` (e.g., Three.js if no 3D)
+7. Update `VERSIONS.json` with new project name and version
+
+## Version Management
+- `VERSIONS.json` and `VERSION` file must stay in sync
+- `package.json` version should also match
+- Follow SemVer (MAJOR.MINOR.PATCH)
+- When releasing: update all three version references, then tag and push
+- Current: see `VERSION` file
+
+## Commands
+```bash
+npm run dev        # Start dev server (port 3000, proxies /api to backend)
+npm run build      # Production build (tsc + vite build)
+npm run preview    # Preview production build
+```
