   Coloca este archivo en: content/docs_content/assets/stylesheets/fracttal-redesign.css
   Y agrégalo a mkdocs.yml DESPUÉS de extra.css y custom.css:

   extra_css:
     - assets/stylesheets/extra.css
     - assets/stylesheets/custom.css
     - assets/stylesheets/fracttal-redesign.css   ← NUEVO

   Aplica:
     · Header con gradiente Fracttal ONE (en vez del 135° linear actual)
     · Tabs nav en blanco con underline Electric Blue (Variante D)
     · Cards Atomic Design con menos saturación (glass sobre fondo claro)
     · Inline code con fondo neutro (quita el efecto lavanda)
     · Tipografía Geist (en vez de Arial)
     · Footer compacto con cyan-glow sutil
