   SSTAPGROUP — hoja de estilos del sitio público
   Concepto: "El Libro Mayor" — tipografía editorial sobre un fondo que evoca
   el papel pautado de un libro contable: reglas finas, cifras tabulares,
   entradas numeradas como asientos contables, sellos y folios.
   Paleta: tomada del logo real de SSTAPGROUP (azul marino + verde), extraída
   por muestreo de píxeles del logo para máxima fidelidad. Los nombres de
   variable ("--brass" etc.) se conservaron para no romper el resto del CSS,
   aunque ahora representan el verde de marca en vez del bronce original.
