%% mob_photos_nif — Erlang NIF module for the photo/video picker + MediaStore
%% enumeration tier-1 plugin.
%%
%% iOS: priv/native/ios/mob_photos_nif.m (Objective-C: PHPickerViewController,
%% iOS 14+, runs out of process so the picker needs no runtime permission; plus
%% the :media permission flow via PHPhotoLibrary). Android:
%% priv/native/jni/mob_photos_nif.zig bridging to the system Photo Picker
%% (PickVisualMedia / PickMultipleVisualMedia) AND MediaStore enumeration
%% (ContentResolver) via the io.mob.photos MobPhotosBridge 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.

%% Enumerate the media library. Async on Android: results land later as
%% {:media, :listed, items} via the deliver thunk. iOS returns
%% {error, unsupported} synchronously.
