/* ============================================================
   A ENTRADA · Transver — folha da página
   O volume óptico: a rolagem muda o plano focal. Cada .plano
   tem uma cota data-z; lente/entrada.js escreve --foco (0..1)
   e --delta (prof − z). Sem JavaScript, os planos ficam em
   fluxo normal — tudo legível de cima a baixo.
   Casca (moldura, topo, eixo, status) herdada da entrada v2.
