   Hubris Network — professional light theme

          tan   #e5aa70 (accents/chips/hover, with dark --on-tan text)
   Contrast rules: body text uses --slate-deep (>=5:1 on white);
   --tan is for large text, decorative rules, or backgrounds
   paired with --on-tan. Body --text on --surface is ~12:1.
