/* 05 · Arquitetura do evento — "A pista de 5 estações".
   Base (sem JS, movimento reduzido, tablet e celular): pista vertical à esquerda com as estações empilhadas.
   .ar-h (desktop, JS): pin com rolagem lateral; o corredor "Sua marca" fica fixo na tela e a pista corre
   sob ele, acendendo cada estação ao passar. */
