/* ===== Layout mobile (<=768px) =====
   Pedido do usuario: as 3 colunas fixas de #content (sidebar 360px | mapa |
   resultado 360px) espremem o mapa ate' ficar inutilizavel em tela pequena.
   Abordagem: em vez de position:fixed pras barras novas, usa flex "em fluxo"
   (order na rail de modulos) -- o app ja e' todo desenhado em torno de
   .screen{height:100vh;overflow:hidden} com cada regiao tendo seu proprio
   overflow-y interno (comentario la' em cima), entao uma barra em fluxo ja
   "empurra" o conteudo sem duplicar altura como padding-bottom, e evita a
   dor de cabeca classica do Safari iOS (barra de URL dinamica nao bate
   sempre com 100vh pra elementos position:fixed). So' o dropdown do menu ≡
   e o FAB de calcular sao overlays de verdade (position:absolute), porque
   precisam flutuar por cima de conteudo, nao empurrar layout. */
