// whose code is a translation key ('error-notAllowed', 'error-board-notAdmin')
// shows that translation. Anything else shows the translated "Something went
// wrong", with the server's own reason after it when it gave one: that reason
// is English, but it is what an admin needs to find the cause.
//
// Before this, each alert() fell back to its own English sentence ("Failed to
// archive board", "Could not add the member.") - 25 of them, untranslated.
