/**
 * Escola 360 — UI Polish (camada final, carregada depois de theme-modern.css)
 *
 * Objetivo: acabamento profissional e consistente em TODAS as páginas.
 *  1. Sidebar sem sobreposição (rodapé compacto, menu rolável com fade).
 *  2. Botão do Assistente IA sempre no canto inferior direito.
 *  3. Botões, cards, tabelas, formulários, badges e estados vazios unificados.
 *  4. Correções de sobreposição: stepper do cadastro, cartões de estatística
 *     estreitos, pílulas de status do cabeçalho, barras fixas de ação.
 *  5. Movimento sutil (entrada de conteúdo, hover) respeitando reduced-motion.
