screen now points to https://turkservis.online/indir and credits the original
project.

+
+Summary of changes made by TurkServis (Apache-2.0, section 4(b)):
+  - Display name changed to "AITURK Mobil"; user-visible "Hermes" / "Hermes
+    Mobile" texts replaced with AITURK branding in all locales.
+  - applicationId changed to online.turkservis.aiturk.mobil (the Kotlin
+    namespace and source packages remain com.m57.hermescontrol).
+  - Turkish translation added (app/src/main/res/values-tr) and Turkish added
+    to the in-app language picker.
+  - Launcher icon replaced with the AITURK mark.
+  - The in-app GitHub self-updater (Hy4ri/hermes-mobile releases) is switched
+    off; builds are distributed from https://turkservis.online/indir.

+    developer.
+
+AITURK and TurkServis names and the AITURK mark are not covered by the
