 * Paleta 100% laranja Sellentt (sem azul) e fundo branco, igual ao site --
 * o site institucional nao tem modo escuro, entao esta base tambem nao tem.
 *
 * Formas extraidas do site institucional:
 *   - laranja de marca #EE7100 (CTA, links, indicador ativo, categorias, tags)
 *   - cantos retos (2px) em botoes e cartoes -- a marca nao usa pilula/rounded
 *   - sombra caracteristica 0 16px 40px rgba(100,114,128,.2) nos cartoes
 *   - tipografia GreycliffCF (fonte proprietaria da Sellentt, licenciada
 *     separadamente). Aqui usamos Poppins como substituta -- geometria
 *     proxima -- ate os arquivos .woff2 da GreycliffCF serem adicionados em
 *     /public/fonts e declarados via @font-face (ver comentario no final).
