 The committed bundle ID `com.therealaleph.mhrv` is reserved for the main release.
 A bundle ID is globally unique across all of Apple, so if you want to ship your

 1. `ios/project.yml` — app target:
-   `PRODUCT_BUNDLE_IDENTIFIER: com.therealaleph.mhrv` → `com.therealaleph.mhrv.pixel`
+   `PRODUCT_BUNDLE_IDENTIFIER: com.therealaleph.mhrv` → `com.therealaleph.mhrv.<suffix>`
 2. `ios/project.yml` — `MhrvTunnel` target (the extension ID **must** stay a child
    of the app ID):
-   `com.therealaleph.mhrv.tunnel` → `com.therealaleph.mhrv.pixel.tunnel`

+   `"com.therealaleph.mhrv.tunnel"` → `"com.therealaleph.mhrv.<suffix>.tunnel"`
 4. (Optional, for a fully independent data container) change the App Group in both

 5. `cd ios && xcodegen generate`, then create the App Store Connect record for the
    new bundle ID.
