/*
 * LP PME — Unimed Porto Alegre
 * Revisão completa de UX: hero fullscreen, modal conversiva, seções polidas.
 * Referência visual: https://lp.unimedpoa.com.br/pme/
 *
 * Decisões de UX documentadas:
 *   1. Hero ocupa 100vh — headline legível, CTA único, sem formulário inline.
 *   2. Formulário em modal overlay — não compete com hero/conteúdo; abre via JS.
 *   3. Sticky CTA bar no topo após scroll — conversão acessível em qualquer ponto.
 *   4. Seções com ritmo visual claro (branco → verde → escuro → foto → verde → footer).
 *   5. Tipografia com contraste AA+ em todas as superfícies.
 *   6. Mobile-first: grids colapsam em coluna única; modal ocupa tela cheia.
