/* ==========================================================================
   Arandu Sentinel — folha de estilos única (visual claro e corporativo)
   Sem build, sem framework. Todas as classes usam o prefixo "sn-" para não
   colidir com estilos antigos durante a migração.
   Fontes: IBM Plex Sans e IBM Plex Mono. Para funcionar sem internet, coloque
   os arquivos .woff2 na pasta "fonts/" ao lado deste CSS (nomes abaixo).
   Se faltarem, o navegador usa a fonte do sistema sem quebrar o layout.
   Ajustes do projeto sobre o arquivo entregue: links-botao (especificidade),
   atributo hidden, cores de nivel, menu fixo e grade, tom do nivel no cartao da
   nota, monograma da marca, alertas, estado vazio e botao de perigo.
