Android: reproducible signed build (keystore and Bazaar RSA key read from outside the repo), Gradle wrapper, build-apk.sh

First time the project has been built: debug and release both produce an APK.
Release refuses to build without keystore or RSA key.

 محصولِ دیجیتال را فقط از راهِ خودش می‌پذیرد. باقیِ اپ همان فرانتِ وب است و با دیپلویِ
 فرانت به‌روز می‌شود، بی‌آن‌که نسخه‌ی تازه‌ی اپ لازم باشد.

 ## پیش از build — سه چیز از پیشخانِ بازار (سنیور / حسابِ شرکت)
 
 | چه | کجا گذاشته می‌شود | وضعیت |
 |---|---|---|
 | اسمِ پکیج | `applicationId` در `app/build.gradle.kts` | `com.tadrisino.app` حدس است؛ تأیید نشده |
-| کلیدِ RSAِ عمومیِ اپ | `BAZAAR_RSA_KEY` در `app/build.gradle.kts` | ندارد؛ بدونِ آن خرید شروع نمی‌شود |
+| کلیدِ RSAِ عمومیِ اپ | `bazaarRsaKey` در فایلِ تنظیماتِ بیرون از ریپو (پایین) | ندارد؛ بدونِ آن build نوعِ release نمی‌شود |
 | SKUِ هر بسته (محصولِ **مصرف‌شدنی**) | پنلِ ادمینِ بک‌اند: `/admin/subscription/plan/` ← «Bazaar sku» | هیچ‌کدام تعریف نشده |
 
 قیمتِ هر محصول در پیشخانِ بازار باید با قیمتِ همان بسته در ادمین یکی باشد؛ سرور مبلغ را از
 بازار نمی‌خواند.
 
+## تنظیماتِ بیرون از ریپو
+
+keystore و کلیدِ RSA هرگز داخلِ ریپو نمی‌آیند. یک فایل با دسترسیِ ۶۰۰ بسازید: `~/.tadrisino/android.properties`
+(یا مسیرِ دلخواه در `TADRISINO_ANDROID_CONFIG`):
+
+```
+storeFile=/مسیر/کامل/tadrisino-release.jks
+storePassword=...
+keyAlias=...
+keyPassword=...
+bazaarRsaKey=<کلیدِ RSA از پیشخانِ بازار، یک خط>
+```
+
+| مقدار | از کجا | اگر نبود |
+|---|---|---|
+| `storeFile` تا `keyPassword` | keystoreِ شرکت. **همان فایلِ APKِ فعلی را امضا کرده؛ نسخه‌ی تازه با کلیدِ دیگر روی بازار آپدیت نمی‌شود.** دو نسخه‌ی پشتیبان در دو جای جدا | build نوعِ release با پیامِ روشن می‌ایستد |
+| `bazaarRsaKey` | پیشخان ← اپ ← پرداخت درون‌برنامه‌ای | build نوعِ release می‌ایستد (نه اپِ بی‌خرید) |
+
 ## build
 
-1. Android Studio ← Open ← همین پوشه‌ی `android/`. Studio خودش Gradle wrapper را می‌سازد.
-2. `Build ← Generate Signed App Bundle / APK`، با کلیدِ امضای شرکت. **کلیدِ امضا را گم نکنید**:
-   بدونِ همان کلید هیچ نسخه‌ی بعدی روی بازار به‌روزرسانی نمی‌شود.
-3. نصب روی گوشی‌ای که کافه‌بازار دارد و با حسابِ تست وارد شده.
+نیازها (یک بار): JDK 17 (`brew install openjdk@17`) و Android SDK با `platforms;android-34` و `build-tools;34.0.0` در `~/Library/Android/sdk`.
+
+```bash
+cd android && ./build-apk.sh
+```
+
+خروجی `android/build-out/Tadrisino-<نسخه>-<versionCode>.apk` است. پیش از هر انتشار `versionCode` را در `app/build.gradle.kts`
+بالا ببرید (بازار نسخه‌ی با شماره‌ی تکراری را نمی‌پذیرد). اسکریپت امضا را می‌سنجد و اثرانگشتِ گواهی را چاپ می‌کند؛ باید با APKِ قبلی یکی باشد.
+APKِ آزمایشی بی‌نیاز از کلید: `./gradlew assembleDebug`.

+#   gradlew start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh gradlew
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/3d91ce3b8caaf77ad09f381f43615b715b53f72c/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
