%% mob_biometric_nif — Erlang NIF module for the biometric tier-1 plugin.
%%
%% iOS: priv/native/ios/mob_biometric_nif.m (Objective-C, LAContext).
%% Android: priv/native/jni/mob_biometric_nif.zig (BiometricPrompt via the
%% io.mob.biometric.MobBiometricBridge 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 NIFs fall back to nif_error until the native merge links one.
