 * loader.css — indicadores de carregamento do MultiVendas.
 *
 * Dois indicadores complementares, ambos usando a cor da loja
 * (--brand-primary / --brand-secondary, lidas de html.brand-scope):
 *
 *   1) .mv-loader-bar     -> barra fina no topo, para navegacao entre paginas
 *   2) .mv-loader-overlay -> veu + spinner central, para acoes na mesma pagina
 *   3) .mv-spinner        -> spinner reutilizavel (tambem inline, em botoes)
 *
 * Os elementos .mv-loader-bar e .mv-loader-overlay sao criados sozinhos pelo
 * loader.js (nao precisa colocar HTML na pagina). Esta folha so estiliza.
