/**
 * Sollu Education - Design System & UI/UX (Estilo Aplicativo iOS / Apple Native)
 * 
 * ============================================================================
 * GUIA DIDÁTICO PARA NÃO-PROGRAMADORES:
 * ============================================================================
 * Este arquivo define a identidade visual ultra-moderna, fluida e minimalista
 * inspirada nos aplicativos nativos do iOS (Apple).
 *
 * Características principais:
 * 1. Cores refinadas: Fundo clean (#F8F9FB), contraste suave e tipografia em grafite escuro.
 * 2. Cantos amplamente arredondados (10px a 24px) com bordas ultrafinas (1px solid rgba(0,0,0,0.06)).
 * 3. Glassmorphism: Efeito de vidro fosco translúcido com backdrop-filter blur.
 * 4. Segmented Controls: Controles de pílulas deslizantes estilo iOS substituindo dropdowns.
 * 5. Dropzones com microinterações ao passar o mouse ou arrastar arquivos.
 * 6. Z-Index rigoroso garantindo compatibilidade total com janelas do WordPress (wp.media).
