/* ============================================================================
   Prisma Capital — brand layer (Optical dark lab)
   Deep blue-black + a hairline optical grid + white light. Colour appears ONLY
   where light refracts (the 3D hero + thin spectral ticks), never as ambient
   gradients. Type: IBM Plex Sans (display/body) + IBM Plex Mono (data/labels).
   Loaded after style.css on strategy pages; its tokens win, so the whole site
   inherits this palette.
