/*
 * header.css — Estilos globais e componentes do header do sistema
 *
 * Inclua este arquivo em TODAS as páginas, logo antes do CSS específico da página:
 *   <link rel="stylesheet" href="../header.css">
 *
 * ⚠️ ESCOPO DESTE ARQUIVO:
 *   Cobre: reset, variáveis de tema, body, barra gradiente, header,
 *          botões de navegação (Voltar / Início), chips de contexto,
 *          school-pill e dropdown de usuário.
 *
 *   NÃO cobre: grid de cards, tabelas, campos de formulário, modais,
 *              ou qualquer elemento exclusivo do body de cada página.
 *
 *   ⚠️ ATENÇÃO — CLASSES COMPARTILHADAS:
 *   As classes .btn-back e .btn-home são estilizadas aqui pensando no header.
 *   Se alguma página reutilizar essas classes no body com visual diferente,
 *   mantenha o CSS sobrescrito no <style> local daquela página.
