/* ===================================================================
   MOBILE TASK OVERLAY — orientação, scroll, botões grandes fixos
   Resolve: em landscape no celular, conteúdo central não rolava e o
   botão "Começar" ficava inacessível atrás dos botões de resposta.
   - .task-stage-area agora tem overflow-y:auto e padding seguro.
   - Botões de resposta vão para uma faixa fixa NA BASE da tela apenas
     durante o trial real (não bloqueiam instruções/botão "Começar").
   - Landscape mobile usa colunas para Stop-Signal e Cued Task-Switching.
   - Adicionado "Orientation Gate" para tarefas que exigem paisagem.
   Heurísticas Nielsen aplicadas:
     1 visibilidade do estado (gate explícito)
     2 linguagem do mundo real (símbolos ←/→ e rótulos claros)
     3 controle do usuário (botão "Encerrar" sempre visível)
     4 consistência (mesmo padrão das três tarefas)
     5 prevenção de erro (alvos grandes ≥ 60px, sem zoom acidental)
     6 reconhecimento > memória (rótulos visíveis)
     7 flexibilidade (responsivo: portrait, landscape, desktop)
     8 estética minimalista
     9 mensagens de erro humanas
     10 ajuda/documentação na própria tarefa
