/* Seletor de período do dashboard RDB (period-filter.js), no design system da Dash:
   botão em pílula na linha da navegação + painel com "Todos os meses" e meses marcáveis.
   Sem sombras: o painel se destaca pela borda mint de 1px. Mês parcial: borda tracejada
   e '*' no rótulo (também no botão). No celular, .pf-hint some e o aviso de parcial fica. */
