/*
 * Portal Pulso — landing estática.
 *
 * Porte da versão React (pulso/web/src/pages/Landing/) para HTML+CSS puro, para
 * publicar num host de estático enquanto o portalpulso.com.br não resolve.
 *
 * As cores são os MESMOS tokens do produto (pulso/web/src/shared/themes/tokens.ts).
 * Marca é uma só: se a página de vendas usar outro azul, o visitante troca de
 * marca ao entrar no app.
 *
 * Sem JavaScript. O FAQ usa <details>, que já é acordeão nativo, e o menu do
 * celular usa um checkbox escondido — as duas coisas que normalmente pedem script.
