// Part 9 of 15 of the operator console app script.
//
// Keyboard review mode, duplicate grouping, and batch decisions.
//
// Load order is significant: these are classic (non-module) scripts sharing one
// global scope, and index.html must keep them in the order listed above/below.
// Splitting is a pure line-range extraction of the former single app.js.
