/* ============================================================
   M&A Gestión de Pruebas — sistema de diseño
   Paleta oficial del manual de marca M&A Ingeniería y Consultoría SAS
   (motivo eólico/solar). Tema único claro, optimizado para lectura en
   exteriores bajo luz solar directa — sin modo oscuro. Tipografías:
   Zilla Slab (encabezados) + IBM Plex Sans (interfaz) + IBM Plex Mono
   (datos/lecturas).

   Nota de accesibilidad: el manual no incluye un rojo, así que --danger
   se derivó aparte (no es un color de marca). Además, #258fbf y #3aaa35
   dan bajo contraste usados como TEXTO pequeño (ver informe), así que
   --accent-text/--success-text/--warning-text son variantes oscurecidas
   del mismo matiz para esos casos puntuales; los botones y rellenos
   sólidos SÍ usan los hex exactos del manual con texto oscuro (#152618)
   encima, tal como se pide para el amarillo.
