//  MioPlugin.swift
//  MioIsland Plugin SDK
//
//  Standalone copy of the MioPlugin protocol from the host CodeIsland app.
//  At runtime, @objc protocol conformance is matched by selector signatures
//  (not module identity), so this duplicate works for .bundle plugins
//  loaded by NativePluginManager.
//
//  DO NOT change the selectors or the @objc-ness — the host walks them
//  via responds(to:) / perform(_:) and any divergence will silently break
//  loading.
