// Patch the freshly-generated Capacitor iOS AppDelegate so calls DEFAULT to the loudspeaker at launch

// TOLERANT: exits 0 and no-ops if the template doesn't match, so it can NEVER fail the build.
// NOTE: the earpiece<->speaker TOGGLE is provided by the local Capacitor plugin package mobile/plugins/
// audio-route (registered by cap sync, like @capacitor/share). This file only sets the launch default.
