expo-image-picker
real browser file-input picker for library; camera uses capture attribute. Full PermissionStatus + ImagePickerErrorResult + writeOnly parity with upstream. Video selection probes a hidden <video> element's loadedmetadata for real width/height/duration (in ms, matching upstream). Image selection reads naturalWidth/naturalHeight; base64 read via FileReader runs in parallel with the metadata probe so the picker returns quickly. Unknown-MIME files fall back to a video probe before giving up.93%
