   Gen IO — site.css  (v2)

   Language: Apple typographic discipline × Kuasa palette.
   - Type: native SF Pro → Inter stack, 600-weight display, tight tracking,
     big scale, one idea per section, generous vertical rhythm.
   - Colour: Kuasa tokens — ink #0B1D3A, blue #2563FF, soft band #F2F4F7,
     night #020b19. One accent only.
   - Surfaces, not boxes: soft fills + hairlines, no border soup, no glows.
