/*
  Diagnóstico de Comunicação da PMMG — 2026
  Folha de estilos institucional.

  Paleta de cores — ORIGEM DOCUMENTADA:
  As cores --pmmg-preto, --pmmg-caqui e --pmmg-vermelho abaixo foram
  extraídas diretamente do Manual de Identidade Visual da PMMG (MIV),
  Caderno 01 | Símbolos Institucionais, seção "Cores" (págs. 26 e 53):
    Cáqui     -> Pantone PMS4515C  | Hex #A08F63 | RGB 160,143,99
    Preto     -> Pantone PMSBLACK  | Hex #373435 | RGB 55,52,53
    Vermelho  -> Pantone PMS7621C  | Hex #AB2328 | RGB 189,53,57
    Branco    -> padrão internacional alternativo (pág. 53) Hex #FEFEFE
  Estas são cores OFICIAIS (não provisórias). O tema do Power BI do projeto
  (tema/Tema_PMMG_Diagnostico.json) usa uma paleta azul/dourado/verde que
  NÃO corresponde ao MIV e por isso foi deliberadamente descartada — ver
  AUDITORIA_DADOS.md, item "Paleta de cores".

  Tipografia: Rawline é a fonte institucional oficial (MIV, pág. 44-45),
  mas nenhum arquivo de fonte (.ttf/.otf/.woff) foi localizado nesta
  máquina. O próprio MIV (pág. 45) prevê fallback: "Na ausência da fonte,
  os usuários poderão utilizar a família tipográfica Arial". Por isso o
  empilhamento abaixo usa Arial/Helvetica/sans-serif, sem baixar fontes
  externas (requisito de funcionamento 100% offline).
