/* Migraine Pilot / Enxaqueca Pilot — site
   Segue a identidade do app (docs/identidade-visual.md, design_system/):
   claro por padrão (fundo #F8F9FA, cards brancos, raio 28, sombra quase
   invisível), acento lilás-índigo #5E5AA8 que nunca é fundo de tela, escuro
   = paleta do "modo conforto" (fundo #111315, sem sombra, contorno sutil).
   Vermelho só representa dor — o site não usa vermelho.
   Fonte Plus Jakarta Sans servida daqui (assets/fonts, OFL), sem Google
   Fonts: o site não faz nenhuma requisição a terceiros. */
