/* ============================================================================
   FenixL — Sistema de diseño del backend
   ----------------------------------------------------------------------------
   Misma marca que la web pública (tinta, brasa, tres voces tipográficas) pero
   con otra misión: aquí se trabaja. Más densidad, menos espectáculo, cero
   animación gratuita. El panel debe leerse rápido a las ocho de la tarde.

   Reglas heredadas del sistema público:
     · ámbar/brasa = acción y calor (solo botones primarios y estado activo)
     · esmeralda   = prueba / algo resuelto
     · niebla      = estructura (bordes, texto secundario)
     · la monoespaciada es para datos: importes, fechas, identificadores
