/* ===========================================================
   NEUROVERSE — visual identity
   Palette sourced from documented MBVISION / INNOVARTISM brand
   material: the live innovartism.com page reports a theme color
   of #050807, and MBVISION's own dark "Tech Edition" working
   palette (ink #0D0B14, violet #9B6BF3, magenta #E0568F,
   teal #3FDDC4, gold #E7B95A) was built from the same site's
   look. Exact site CSS could not be retrieved in this
   environment, so this palette is the closest verified match
   rather than an invented one — swap CSS variables below if
   brand supplies exact hex values later.
