   METRIX LAB - hero.css
   Section: #hero (page order 2). Full-viewport hero on pure black with the
   cursor-reactive particle canvas behind content + radial vignette depth.
   Every rule scoped under #hero so it never collides with other sections.
   Reuses contract tokens only - no hardcoded colors that already have a token.
