%% mob_screencast_nif — Erlang NIF module for the screen-capture tier-1 plugin.
%%
%% Android: priv/native/jni/mob_screencast_nif.zig bridges to the Kotlin
%% io.mob.screencast.MobScreencastBridge (MediaProjection capture + a MediaCodec
%% AVC encoder; encoded NAL units are handed back via nativeDeliverScreencastFrame).
%% iOS: priv/native/ios/mob_screencast_nif.m (ReplayKit / ScreenCaptureKit capture +
%% a VideoToolbox H264 encoder). 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.
