/* ══════════════════════════════════════════════════════════════
   Portal GSZ Admin — Login CSS v2.3 (MOBILE-FIRST)
   v2.3 — marca no topo do formulário, distribuição vertical do showcase
          e painel mais largo em monitor grande (menos vazio).
   
   Reescrito a partir do v2.1. Nenhuma classe foi removida — o HTML
   continua idêntico. O que mudou:
     · Base agora é o CELULAR; o split-screen entra a partir de 900px
     · Inputs 16px (impede o zoom automático do iOS ao focar)
     · 100dvh + safe-area-inset (barra do navegador e notch)
     · Alvos de toque de 44px+ (botão de senha e CTA)
     · Partículas e backdrop-filter só no desktop (bateria/frame rate)
     · Blocos responsivos unificados — acabou a briga 820/480 × 900/560
