/**
 * PA Chat ao Vivo — estilos do widget.
 *
 * Direção de design: "jurídico-profissional + vivacidade de live".
 * - Índigo (#4054B2) como cor principal; verde (#23A455) no indicador AO VIVO.
 * - Tipografia HERDADA do tema (font: inherit) — decisão intencional para
 *   o widget se integrar à página já-branded do professor, em vez de
 *   competir com uma fonte de display própria.
 * - Âncoras memoráveis: badge AO VIVO pulsante, avatares coloridos com a
 *   inicial do nome e entrada suave das mensagens.
 *
 * Tudo escopado sob .pa-chat. !important é usado apenas nos pontos onde o
 * tema/Elementor costuma sobrescrever (inputs, botões, links, listas).
