   landings-common.css — Estilos compartilhados das landing pages de SEO
   (Dividindo.com). Extraído do <style> inline dos 3 HTMLs standalone:
   alternativa-splitwise, dividir-contas-churrasco, dividir-contas-republica.

   O que mora AQUI: design tokens (:root), reset, base do body, textura de
   papel, navbar e footer compartilhados, pills, botões e section-tag.
   O CSS específico de cada landing (hero, tabela, ticket, mock dashboard,
   etc.) permanece inline no <style> de cada view.
