/*
 * GLOBAL THEME ENGINE — RST GSM
 * ------------------------------------------------------------------
 * Regras GLOBAIS e de baixo risco que consomem as variáveis --theme-*
 * definidas dinamicamente por includes/helpers/theme_engine.php
 * (renderGlobalThemeStyleBlock).
 *
 * Este arquivo NÃO sobrescreve nenhum sistema de design existente
 * (--uds-*, --ads-*, --auth-*) — essas pontes já ficam no <style> inline
 * gerado pelo PHP. Aqui ficam apenas:
 *   1) o "background ambiente" global (gradients leves, sem imagens);
 *   2) baseline para elementos genéricos usando :where() (especificidade
 *      zero — qualquer outra regra existente sempre vence, então isto
 *      nunca quebra nada que já tenha estilo);
 *   3) classes utilitárias opcionais citadas no pedido (.card, .modal,
 *      .alert, .badge, .pagination, .tabs) para quem ainda não usa um
 *      design system específico;
 *   4) toques globais de identidade (seleção de texto, foco, scrollbar).
 *
 * Performance: só gradients/CSS variables, sem imagens pesadas, sem JS.
