/* Design system compartilhado das páginas públicas fora do template
   principal (login, 2ª via de boleto, recuperar senha) — extraído em
   19/09 porque as 3 páginas tinham o mesmo bloco de CSS colado 3x
   (achado do AUDIT01: CSS inline repetitivo que deveria estar
   centralizado). Qualquer ajuste visual de marca (cor, fonte, gradiente)
   feito aqui vale pras 3 de uma vez — cada página só mantém no próprio
   <style> o que é exclusivo dela. */
