/* ===== MENU DE CONSTRUÇÃO EM MODAL (js/systems/ui/BuildMenuUI.js) =====
   Clicar numa categoria abre #build-modal com os cards (#building-items mora aqui dentro); um clique no card
   mostra as informações à direita (no celular, em tela cheia) com a prévia 3D girando e o botão Construir
   sempre visível no rodapé. Abre sem animação longa (120 ms): é o caminho de toda obra.
   Não pausa o jogo (não está em isInfoPopupOpen). z-index 97: abaixo do rastreador de eventos (98), dos
   toasts (99) e do tutorial (200), para o destaque do tutorial passar por cima. */
