  /* ---------- Superfícies e limites ----------
     Valores herdados do Framer eram quase invisíveis: --border #eaecf0 dava
     1.18:1 contra o branco e --bg-soft #f9fafb dava 1.05:1. Em tela clara ou
     com brilho alto, card e fundo viravam a mesma superfície e as faixas
     alternadas de seção sumiam.

     Recalibrados por medição (razão de contraste WCAG contra #ffffff):
       --border    #cbd1da  1.54:1  (era 1.18)  limite perceptível sem virar traço
       --border-2  #b4bdcb  1.90:1  (era 1.47)  estado forte/hover, um degrau acima
       --bg-soft   #f1f3f7  1.11:1  (era 1.05)  faixa alternada de fato visível
       --bg-softer #f8f9fb  1.06:1  (era 1.03)

     3:1 (WCAG 1.4.11) numa borda de card deixaria o visual pesado demais; o
     alvo aqui é perceptibilidade, com a separação reforçada por elevação
     (ver --shadow-card abaixo) em vez de só pela linha. */
