<div class="desc"><p>Constructs the retained-UI tree you declared in a <code>ui</code> block, laying out its panels, labels, and buttons and loading any skins or images they reference. Call it once during a <code>Start</code>-phase handler, after loading any fonts the UI needs, and before you open a screen with <code>ui_open</code> or draw it with <code>ui_render</code>. Because the UI is declared as data and built in one step, the game code only has to build it, open it, and read clicks. It takes no arguments.</p></div>
