   Palette extraída da logo: verde-palmeira (símbolo/wordmark), dourado
   do sol, azul do mar e coral da onda. Tipografia: Baloo 2 (display,
   arredondada, ar tropical/praiano) + Nunito Sans (corpo, legibilidade).
   Nota de diferenciação: raio assimétrico nos botões/cards, divisor em
   "dunas" (em vez da fita ondulada padrão), cards de modelo com canto
   dobrado e cards de diferencial com selo numerado.
