rebuild the app on a typed, modular structure wired to the real API

The whole app lived in one 3,071-line App.tsx on a Figma scaffold (60 unused packages, 45 unused UI components, no type-check). The live site could not reach the backend, Persian-keyboard digits were erased from the phone field, guests were signed out after an hour, "mark read" hit a method the server does not accept (405), and iOS Safari blocked the payment window. What changed: - src/ split into api/ (one typed client: timeouts, GET retry, single-flight refresh, SSE), screens/ (one file each), components/, state/, nav/, lib/. - The API address is configuration only: public/config.js at runtime, then VITE_API_BASE_URL at build time, then same-origin /api. No domain in code. - Responsive shell instead of a fixed 390x844 phone frame; self-hosted Vazirmatn instead of Google Fonts; strict TypeScript, `npm run build` type-checks first. - Everything on the handoff list: tutor answers keep their line breaks, have thumbs up/down, follow-ups, "from the book" badge, retry, history that survives tab switches and reloads, "why was I wrong" from a wrong answer with questionId; question reports; hearts with maxHearts/unlimited and a no-hearts screen with the refill time; result screen and a visible error when lesson completion fails; subscription status, badge, discount code before the gateway and the payment-return message; guest refresh token; 6-digit OTP with resend timer; age saved as a Jalali birthYear; PATCH read-all; leaderboard refetched on open with "you" highlighted; selected companion shown across the app; logout that revokes the refresh token. - New screens for endpoints that had none: profile, streak calendar, support tickets and bug reports, parents, invite-a-friend (with ?ref= tracking), guest-to-phone upgrade. - Browser/phone back button walks the screen stack. Checked with a headless-Chrome walkthrough against a local backend at 390x844 and 360x740 (fresh guest: onboarding, setup, a full lesson, map, island sheet, every tab and sub-screen, one real tutor question, reload, logout): no console errors, no failed API calls. Real SMS login and a real Zarinpal payment were not exercised. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

+# تدریسینو — فرانتِ اپِ ریاضی
+
+اپِ وبِ موبایل‌محورِ تدریسینو (React + TypeScript + Vite + Tailwind). بک‌اندش ریپوی
+جداست (`Tadrisino/MathApp`)؛ قراردادِ API در `/api/docs/` همان بک‌اند است.
+
+## راه‌اندازی
+
+```bash
+npm install
+npm run dev          # http://localhost:5173
+```
+
+در حالتِ توسعه، درخواست‌های `/api` از خودِ Vite به بک‌اند پاس داده می‌شوند، پس CORS
+مطرح نیست. پیش‌فرض بک‌اندِ محلی است (`python manage.py runserver` روی پورتِ ۸۰۰۰).
+بدونِ بک‌اندِ محلی، یک فایلِ `.env.development.local` بسازید:
+
+```bash
+VITE_DEV_PROXY_TARGET=https://api.math.tadrisino2.ir
+```
+
+⚠️ آن‌وقت هر کاری در اپ بکنید روی دیتابیسِ واقعی نوشته می‌شود.
+
+| دستور | کار |
+|---|---|
+| `npm run dev` | سرورِ توسعه |
+| `npm run typecheck` | بررسیِ نوع‌ها (strict) |
+| `npm run build` | type-check و بعد build در `dist/` |
+| `npm run preview` | اجرای همان build |
+
+## آدرسِ بک‌اند و عوض کردنِ دامنه
+
+دامنه هیچ‌جای کد نیامده. آدرسِ API به این ترتیب خوانده می‌شود
+(`src/config.ts`):
+
+1. **`dist/config.js`** (از `public/config.js`) — در زمانِ اجرا. بعد از build هم روی
+   سرور قابلِ ویرایش است و build دوباره نمی‌خواهد.
+2. **`VITE_API_BASE_URL`** — در زمانِ build، از `.env.production`.
+3. **`/api`** — هم‌دامنه، وقتی nginxِ دامنه‌ی فرانت مسیرِ `/api` را به بک‌اند پراکسی کند.
+
+برای جابه‌جایی دامنه:
+
+- **سریع، بدونِ build:** روی سرور در `dist/config.js` بنویسید
+  `apiBaseUrl: "https://api.new-domain.ir/api"` و کشِ CDN را برای همین فایل پاک کنید.
+- **ماندگار:** خطِ `VITE_API_BASE_URL` در `.env.production` را عوض کنید و build بگیرید.
+- **سمتِ بک‌اند** هم دامنه‌ی تازه‌ی فرانت باید مجاز باشد (`FRONTEND_URL` در `.env`
+  بک‌اند). جزئیات در `docs/operations.md` همان ریپو.
+
+## دیپلوی
+
+```bash
+npm ci && npm run build
+```
+
+محتوای `dist/` را سرو کنید. اپ مسیرِ جدا (route) ندارد و همه‌چیز از `/` بار می‌شود؛
+فقط `index.html` و `config.js` نباید طولانی کش شوند (باقیِ فایل‌ها نامِ hashدار دارند).
+درگاهِ پرداخت کاربر را به `/?orderId=…&status=…` برمی‌گرداند و لینکِ دعوت
+`/?ref=CODE` است؛ هر دو را خودِ اپ می‌خواند.
+
+## ساختار
+
+```
+src/
+  config.ts            آدرسِ API (بالا را ببینید)
+  api/                 تنها درِ ارتباط با سرور — هیچ جای دیگر fetch نمی‌زند
+    http.ts            timeout، تکرارِ GET، refreshِ تک‌نسخه‌ای، SSE
+    index.ts           یک تابع برای هر اندپوینت
+    types.ts           شکلِ پاسخ‌ها، از روی پاسخِ واقعیِ سرور
+  app/                 App (جریانِ ورود) و MainApp (تب‌ها و صفحه‌ها)
+  nav/                 ناوبریِ پشته‌ای، هماهنگ با دکمه‌ی back گوشی
+  state/               داده‌ی مشترک (پروفایل، نقشه، …) و گفتگوی دستیار
+  screens/             یک فایل برای هر صفحه
+  components/          اجزای مشترک (سربرگ، برگه‌ی پایین، …)
+  mascots/             سه‌یار: سیگما، دلتا، پی
+  lib/                 اعدادِ فارسی، تاریخِ شمسی، صدا، localStorage
+```
+
+قاعده‌ها:
+
+- **اعداد:** برای نمایش `toFa`، برای ورودی `digitsOnly` (کیبوردِ فارسی ارقامِ
+  `۰-۹` می‌فرستد و `\d` در JS آن‌ها را نمی‌شناسد).
+- **رنگ‌ها** در `src/styles/index.css` (`@theme`) تعریف شده‌اند: `bg-coral`، `text-ink`، …
+- **خطا:** پیامِ کاربر همیشه از `friendlyError` می‌آید، نه متنِ خامِ سرور.
+- **کلاینت را از حافظه ننویسید.** قرارداد را از `/api/docs/` بک‌اند بخوانید و تغییرِ
+  `types.ts` را با پاسخِ واقعیِ سرور بسنجید.

-System Guidelines
-
-Use this file to provide the AI with rules and guidelines you want it to follow.
-This template outlines a few examples of things you can add. You can add your own sections and format it to suit your needs
-
-TIP: More context isn't always better. It can confuse the LLM. Try and add the most important rules you need
-
-# General guidelines
-
-Any general rules you want the AI to follow.
-For example:
-
-* Only use absolute positioning when necessary. Opt for responsive and well structured layouts that use flexbox and grid by default
-* Refactor code as you go to keep code clean
-* Keep file sizes small and put helper functions and components in their own files.
-
--------------
-
-# Design system guidelines
-Rules for how the AI should make generations look like your company's design system
-
-Additionally, if you select a design system to use in the prompt box, you can reference
-your design system's components, tokens, variables and components.
-For example:
-
-* Use a base font-size of 14px
-* Date formats should always be in the format “Jun 10”
-* The bottom toolbar should only ever have a maximum of 4 items
-* Never use the floating action button with the bottom toolbar
-* Chips should always come in sets of 3 or more
-* Don't use a dropdown if there are 2 or fewer options
-
-You can also create sub sections and add more specific details
-For example:
-
-
-## Button
-The Button component is a fundamental interactive element in our design system, designed to trigger actions or navigate
-users through the application. It provides visual feedback and clear affordances to enhance user experience.
-
-### Usage
-Buttons should be used for important actions that users need to take, such as form submissions, confirming choices,
-or initiating processes. They communicate interactivity and should have clear, action-oriented labels.
-
-### Variants
-* Primary Button
-  * Purpose : Used for the main action in a section or page
-  * Visual Style : Bold, filled with the primary brand color
-  * Usage : One primary button per section to guide users toward the most important action
-* Secondary Button
-  * Purpose : Used for alternative or supporting actions
-  * Visual Style : Outlined with the primary color, transparent background
-  * Usage : Can appear alongside a primary button for less important actions
-* Tertiary Button
-  * Purpose : Used for the least important actions
-  * Visual Style : Text-only with no border, using primary color
-  * Usage : For actions that should be available but not emphasized

-# اتصال به بک‌اند
-
-کلِ ارتباط با سرور از همین پوشه رد می‌شود. **هیچ‌جای اپ مستقیم `fetch` نزنید** —
-مدیریتِ توکن، تکرارِ درخواست و رفتارِ درستِ خطا اینجا یک‌جا حل شده‌اند.
-
-## راه‌اندازی
-
-**هیچ تنظیماتی لازم نیست.** به‌طورِ پیش‌فرض به بک‌اندِ مشترک
-(`https://api.math.tadrisino2.ir/api`) وصل می‌شود:
-
-```bash
-npm install
-npm run dev
-```
-
-فقط اگر بک‌اند را روی ماشینِ خودتان بالا آورده‌اید:
-
-```bash
-cp .env.example .env      # و خطِ VITE_API_BASE_URL را باز کنید
-```
-
-برای اینکه ببینید اتصال برقرار است، یک خط کافی‌ست (بعداً پاکش کنید):
-
-```tsx
-import { ConnectionCheck } from '@/api/ConnectionCheck';
-// داخلِ خروجیِ App:
-<ConnectionCheck />
-```
-
-گوشه‌ی صفحه سبز می‌شود و فهرستِ پایه‌ها را از سرور نشان می‌دهد، یا قرمز
-می‌شود و می‌گوید دقیقاً کجای کار می‌لنگد.
-
-## استفاده
-
-```tsx
-import { api, ApiError } from '@/api';
-
-const grades  = await api.grades();
-const home    = await api.home();                    // پایه‌ی خودِ کاربر
-const intro   = await api.lessons.intro(lessonId);
-const answer  = await api.ai.ask('این رو نفهمیدم', { lessonId });
-```
-
-### ورود
-
-```tsx
-await api.auth.guest(deviceId);                 // «شروع سریع»، بدونِ شماره
-// یا
-const { devOtp } = await api.auth.requestOtp('09120000000');
-await api.auth.login('09120000000', otp);       // نامِ فیلد در سرور otp است
-```
-
-توکن خودش در `localStorage` ذخیره می‌شود و به هر درخواست اضافه می‌گردد.
-
-### خطاها
-
-```tsx
-try {
-  await api.ai.ask(text, { lessonId });
-} catch (error) {
-  if (error instanceof ApiError) {
-    if (error.isRateLimited) { /* ۴۲۹ — خیلی سریع پرسیده */ }
-    if (error.isProviderDown) { /* ۵۰۳ — سرویسِ AI موقتاً قطع */ }
-    if (error.isNetwork) { /* اصلاً نرسید یا timeout */ }
-  }
-}
-```
-
-## چرا این‌قدر ملاحظه در `client.ts`
-
-هر تکه‌اش برای حالتی‌ست که فقط زیرِ فشار پیش می‌آید:
-
-| مسئله | اگر نباشد چه می‌شود |
-|---|---|
-| `timeout` روی هر درخواست | یک بک‌اندِ کند سوکت‌ها را باز نگه می‌دارد؛ مرورگر به سقفِ ۶ درخواستِ همزمان می‌خورد و کلِ اپ قفل می‌شود |
-| backoff با **jitter** | هزار کلاینت بعد از یک خطا *همزمان* دوباره می‌زنند و موجِ دوم سرور را می‌خواباند |
-| تکرارِ خودکار فقط روی `GET` | تکرارِ `POST` یعنی سفارش یا پاسخِ تکراری |
-| `Idempotency-Key` روی ثبتِ پاسخ و سفارش | دابل‌کلیکِ کاربر دو بار XP یا دو سفارش می‌سازد |
-| `refresh` تک‌نسخه‌ای | ۲۰ درخواستِ همزمانِ ۴۰۱ ⇒ ۲۰ بار refresh ⇒ سرور همه را throttle می‌کند |
-| ادغامِ `GET`های یکسان | دو کامپوننت که با هم یک چیز می‌خواهند، دو برابر بار می‌سازند |
-| احترام به هدرِ `Retry-After` | بک‌اند صریح می‌گوید چقدر صبر کن؛ نادیده گرفتنش throttle را طولانی‌تر می‌کند |
-
-`credentials: 'omit'` هم عمدی‌ست: احرازِ هویت توکنِ Bearer در هدر است و سمتِ
-سرور `CORS_ALLOW_CREDENTIALS=False` تنظیم شده. عوضش نکنید.
-
-## چیزی که هنوز نیست
-
- صفحه‌ی ورود در اپ وجود ندارد؛ `api.auth` آماده است ولی UI ندارد.
- `api.home()` ساختارِ واقعیِ درس‌ها را می‌دهد، ولی وصل کردنش به صفحه‌ها
-  هنوز انجام نشده — این PR عمداً `App.tsx` را دست نزده تا با کارِ در جریان
-  تصادف نکند.
