 `flatpak run com.randogoth.carrier`. Inside the sandbox the app keeps its
 config under `~/.var/app/com.randogoth.carrier/config/carrier`, so a flatpak
 install starts with a fresh identity rather than the dev build's account.

+### Windows

+Install MSYS2 (`winget install MSYS2.MSYS2`), open the **MSYS2 MINGW64**
+shell, and run the one-command script from the carrier checkout:
+
+    git clone ssh://git@code.randogoth.com:2222/randogoth/carrier.git
+    cd carrier && windows/setup.sh
+
+`windows/setup.sh` installs the GTK and Rust stack into MSYS2, clones fumi
+next to carrier if it is missing, builds, and bundles carrier.exe with the
+GTK runtime into `dist/` and a zip — the complete Windows distribution. The
+app keeps its config in `%APPDATA%\carrier`. If MSYS2 updates its core
+mid-run the shell may close; rerun the script and it continues. Cloning
+over SSH needs the key in `~/.ssh` inside the MSYS2 home.
