%% mob_scanner_nif — Erlang NIF module for the QR/barcode scanner tier-1 plugin.
%%
%% iOS: priv/native/ios/mob_scanner_nif.m (Objective-C: AVCaptureMetadataOutput
%% in a full-screen view controller). Android: priv/native/jni/mob_scanner_nif.zig
%% bridging to the plugin-owned io.mob.scanner.MobScannerActivity (CameraX +
%% ML Kit BarcodeScanning) via the io.mob.scanner.MobScannerBridge Kotlin
%% bridge. Both register this module via ERL_NIF_INIT and are statically
%% linked into the host binary on device. On a host dev build neither is
%% linked, so on_load tolerates the failure and the NIF falls back to
%% nif_error until the native merge links one.
