   ASSINA.AI — VITRINE DE PLANOS (#planos)
   Espelha os cards da tela /plans do app (web-ui: src/sections/plans):
   alternador mensal/anual, pacotes, preço, botão e lista do que está incluído.

   Mobile first: a base é o celular (um card por vez, escolhido no seletor);
   os @media (min-width) só acrescentam espaço e, a partir de 992px, as colunas.
