/* ============================================================
   UpToAI — Landing page (tráfego pago, Fase B)
   Marca FECHADA 28/07 — identidade própria (independente da S4S).
   Cores oficiais (uptoai-marca-final/LEIA-ME.md):
   grafite #2D2C2E · dourado #BE9650 · fundo escuro #18171C
   Sistema: grafite = texto/estrutura/contorno; dourado = acento
   (CTA, filetes, números, ícones de destaque). Fundos sempre
   claros; cor forte só em detalhe (regra da marca).
   As variáveis mantêm os nomes antigos (--navy/--blue/--magenta)
   para minimizar a troca; os VALORES agora são os da marca.
