+# Copilot Instructions for Vontor CZ
+
+## Overview
+This monorepo contains a Django backend and a Vite/React frontend, orchestrated via Docker Compose. The project is designed for a Czech e-marketplace, with custom payment integrations and real-time features.
+
+## Architecture
+- **backend/**: Django project (`vontor_cz`), custom `account` app, and third-party payment integrations (`thirdparty/`).
+  - Uses Django REST Framework, Channels (ASGI), Celery, and S3/static/media via `django-storages`.
+  - Custom user model: `account.CustomUser`.
+  - API docs: DRF Spectacular (`/api/schema/`).
+- **frontend/**: Vite + React + TypeScript app.
+  - Organized by `src/api/`, `components/`, `features/`, `layouts/`, `pages/`, `routes/`.
+  - Uses React Router layouts and nested routes (see `src/layouts/`, `src/routes/`).
+  - Uses Tailwind CSS for styling (configured via `src/index.css` with `@import "tailwindcss";`). Prefer utility classes over custom CSS.
+
+## Developer Workflows
+- **Backend**
+  - Local dev: `python manage.py runserver` (or use Docker Compose)
+  - Migrations: `python manage.py makemigrations && python manage.py migrate`
+  - Celery: `celery -A vontor_cz worker -l info`
+  - Channels: Daphne/ASGI (see Docker Compose command)
+  - Env config: `.env` files in `backend/` (see `.gitignore` for secrets)
+- **Frontend**
+  - Install: `npm install`
+  - Dev server: `npm run dev`
+  - Build: `npm run build`
+  - Preview: `npm run preview`
+  - Static assets: `src/assets/` (import in JS/CSS), `public/` (referenced in HTML)
+
+## Conventions & Patterns
+- **Backend**
+  - Use environment variables for secrets and config (see `settings.py`).
+  - Static/media files: S3 in production, local in dev (see `settings.py`).
+  - API versioning and docs: DRF Spectacular config in `settings.py`.
+  - Custom permissions, filters, and serializers in each app.
+- **Frontend**
+  - Use React Router layouts for shared UI (see `src/layouts/`, `LAYOUTS.md`).
+  - API calls and JWT handling in `src/api/`.
+  - Route definitions and guards in `src/routes/` (`ROUTES.md`).
+  - Use TypeScript strict mode (see `tsconfig.*.json`).
+  - Linting: ESLint config in `eslint.config.js`.
+  - Styling: Tailwind CSS is present. Prefer utility classes; keep minimal component-scoped CSS. Global/base styles live in `src/index.css`. Avoid inline styles and CSS-in-JS unless necessary.
+
+### Frontend API Client (required)
+All frontend API calls must use the shared client at frontend/src/api/Client.ts.
+
+- Client.public: no cookies, no Authorization header (for public Django endpoints).
+- Client.auth: sends cookies and includes Bearer token; auto-refreshes on 401 (retries up to 2x).
+- Centralized error handling: subscribe via Client.onError to show toasts/snackbars.
+- Tokens are stored in cookies by Client.setTokens and cleared by Client.clearTokens.
+
+Example usage (TypeScript)
+```ts
+import Client from "@/api/Client";
+
+// Public request (no credentials)
+async function listPublicItems() {
+  const res = await Client.public.get("/api/public/items/");
+  return res.data;
+}
+
+// Login (obtain tokens and persist to cookies)
+async function login(username: string, password: string) {
+  // Default SimpleJWT endpoint (adjust if your backend differs)
+  const res = await Client.public.post("/api/token/", { username, password });
+  const { access, refresh } = res.data;
+  Client.setTokens(access, refresh);
+}
+
+// Authenticated requests (auto Bearer + refresh on 401)
+async function fetchProfile() {
+  const res = await Client.auth.get("/api/users/me/");
+  return res.data;
+}
+
+function logout() {
+  Client.clearTokens();
+  window.location.assign("/login");
+}
+
+// Global error toasts
+import { useEffect } from "react";
+function useApiErrors(showToast: (msg: string) => void) {
+  useEffect(() => {
+    const unsubscribe = Client.onError((e) => {
+      const { message, status } = e.detail;
+      showToast(status ? `${status}: ${message}` : message);
+    });
+    return unsubscribe;
+  }, [showToast]);
+}
+```
+
+Vite env used by the client:
+- VITE_API_BASE_URL (default: http://localhost:8000)
+- VITE_API_REFRESH_URL (default: /api/token/refresh/)
+- VITE_LOGIN_PATH (default: /login)
+
+Notes
+- Public client never sends cookies or Authorization.
+- Ensure Django CORS settings allow your frontend origin. See backend/vontor_cz/settings.py.
+- Use React Router layouts and guards as documented in frontend/src/routes/ROUTES.md and frontend/src/layouts/LAYOUTS.md.
+
+## Integration Points
+- **Payments**: `thirdparty/` contains custom integrations for Stripe, GoPay, Trading212.
+- **Real-time**: Django Channels (ASGI, Redis) for websockets.
+- **Task queue**: Celery + Redis for async/background jobs.
+- **API**: REST endpoints, JWT auth, API key support.

+/**
+USAGE EXAMPLES (TypeScript/React)
+
+Import the client
+--------------------------------------------------
+import Client from "@/api/Client";
+
+
+Login: obtain tokens and persist to cookies
+--------------------------------------------------
+async function login(username: string, password: string) {
+  // SimpleJWT default login endpoint (adjust if your backend differs)
+  // Example backend endpoint: POST /api/token/ -> { access, refresh }
+  const res = await Client.public.post("/api/token/", { username, password });
+  const { access, refresh } = res.data;
+  Client.setTokens(access, refresh);
+  // After this, Client.auth will automatically attach Authorization header
+  // and refresh when receiving a 401 (up to 2 retries).
+}
+
+
+Public request (no cookies, no Authorization)
+--------------------------------------------------
+// The public client does NOT send cookies or Authorization.
+async function listPublicItems() {
+  const res = await Client.public.get("/api/public/items/");
+  return res.data;
+}
+
+
+Authenticated requests (auto Bearer header + refresh on 401)
+--------------------------------------------------
+async function fetchProfile() {
+  const res = await Client.auth.get("/api/users/me/");
+  return res.data;
+}
+
+async function updateProfile(payload: { first_name?: string; last_name?: string }) {
+  const res = await Client.auth.patch("/api/users/me/", payload);
+  return res.data;
+}
+
+
+Global error handling (UI notifications)
+--------------------------------------------------
+import { useEffect } from "react";
+
+function useApiErrors(showToast: (msg: string) => void) {
+  useEffect(function () {
+    const unsubscribe = Client.onError(function (e) {
+      const { message, status } = e.detail;
+      showToast(status ? String(status) + ": " + message : message);
+    });
+    return unsubscribe;
+  }, [showToast]);
+}
+
+// Note: Network connectivity issues trigger an alert and also dispatch api:error.
+// All errors are logged to console for developers.
+
+
+Logout
+--------------------------------------------------
+function logout() {
+  Client.clearTokens();
+  window.location.assign("/login");
+}
+
+
+Route protection (PrivateRoute)
+--------------------------------------------------
+// If you created src/routes/PrivateRoute.tsx, wrap your protected routes with it.
+// PrivateRoute checks for "access_token" cookie presence and redirects to /login if missing.
+
+// Example:
+// <Routes>
+//   <Route element={<PrivateRoute />} >
+//     <Route element={<MainLayout />}>
+//       <Route path="/" element={<Dashboard />} />
+//       <Route path="/profile" element={<Profile />} />
+//     </Route>
+//   </Route>
+//   <Route path="/login" element={<Login />} />
+// </Routes>
+
+
+Refresh and retry flow (what happens on 401)
+--------------------------------------------------
+// 1) Client.auth request receives 401 from backend
+// 2) Client tries to refresh access token using refresh_token cookie
+// 3) If refresh succeeds, original request is retried (max 2 times)
+// 4) If still 401 (or no refresh token), tokens are cleared and user is redirected to /login
+
+
+Environment variables (optional overrides)
+--------------------------------------------------
+// VITE_API_BASE_URL      default: "http://localhost:8000"
+// VITE_API_REFRESH_URL   default: "/api/token/refresh/"
+// VITE_LOGIN_PATH        default: "/login"
