/*
 * Design system do NfseSaaS — portado de um mockup aprovado (visual
 * moderno: sidebar escura fixa, topbar com blur, cards com sombra
 * suave, badges em pill, botões com leve elevação no hover).
 *
 * Decisão importante: em vez de introduzir um conjunto de classes
 * paralelo ao Bootstrap, as classes do Bootstrap já usadas em TODAS as
 * views (.card, .btn, .btn-primary, .badge, .form-control, .form-select,
 * table) foram RESTILIZADAS aqui pra ficar com a cara do mockup. Isso
 * significa que nenhuma view precisou ser reescrita — o efeito visual
 * se propaga globalmente só por herdar este arquivo + o novo _Layout.
 *
 * O "shell" (sidebar/topbar/app/content) é próprio (não é AdminLTE) —
 * removemos o AdminLTE de propósito: além de mais simples, ele foi a
 * causa do bug de "tudo preto" anterior (seguia o dark mode do SO).
