//
//  ChineseAppDetector.swift
//  MioIsland Music Plugin
//
//  Detects whether a Chinese desktop music app (QQ 音乐 / 网易云音乐 / 酷狗)
//  is currently running. These apps do not publish their Now Playing state
//  to MediaRemote and do not expose a scripting dictionary, so we cannot
//  read tracks from them. When detected, the UI surfaces a polite message
//  telling the user to switch to the web player instead of showing an empty
//  or misleading Now Playing view.
