/* ==========================================================================
   OTTO LOUZA DIGITAL AGENCY — Landing Page V1
   Design tokens vindos do brand brief (branding.md).

   Tipografia: sistema de 3 famílias (pendência #10 do brief — recomendação
   de design, ainda não confirmada pela Otto):
   - Space Grotesk (--font-display): títulos H1/H2/H3, botões, wordmark.
     Geométrica com personalidade técnica, sem cair em fonte "futurista"
     genérica — mantém peso editorial/premium.
   - Inter (--font-body): parágrafos e texto corrido. Altíssima legibilidade,
     padrão de interfaces premium/SaaS.
   - JetBrains Mono (--font-mono): eyebrows, section-labels, números de stat,
     índices de plano, footer-headings — a "camada técnica" do sistema.
     Mono só aparece em rótulos curtos e dados (nunca em texto corrido),
     o mesmo princípio usado em produtos fintech/dev-tools premium
     (Stripe, Linear) pra comunicar precisão sem parecer sci-fi.

   z-index crescente manual.

   Só Hero/Sobre/Método (.is-pinned) ficam "presas" (position: sticky) —
   grudam no topo até a próxima seção subir e cobrir. Serviços e Planos
   ficam de fora de propósito: têm mais conteúdo que uma tela (7 itens / 3
   cards, principalmente no mobile), e uma seção presa só mostra a fatia do
