/* =====================================================================
   DeCam — hoja de estilos (assets/css/styles.css)

   Cómo está organizada:
     1. Fuentes autoalojadas (carpeta assets/fonts)
     2. Tokens de diseño: colores, tipografías y medidas  ← si querés cambiar
        un color o una fuente, tocá SOLO esta sección
     3. Base: reset mínimo y tipografía general
     4. Componentes reutilizables: botones, etiquetas, notas
     5. Secciones, en el mismo orden que index.html
     6. Ajustes para celular (media queries)

   Concepto de diseño: "expediente". Columna de lectura a la izquierda,
   reglas finas, etiquetas en monoespaciada (como carátulas de causa),
   y el navy de la marca reservado para el inicio, la tarjeta del CTO y el pie.
