/* =====================================================================
   styles.css — painel de índices IPCA e IGP-M
   ---------------------------------------------------------------------
   Sistema visual: cada índice tem uma cor própria que o acompanha em
   todo o painel (IPCA = azul, IGP-M = cobre) — nos cartões, no gráfico
   e nas tabelas. O restante é neutro para não competir com os dados.
   Números usam algarismos tabulares para alinhar em colunas.
