/* ============================================================
   PRO-MIND — Design System v2 (Elite Client Tier)

   Direction: quiet luxury. Boutique advisory-to-the-boardroom —
   closer to a private bank or family office than a SaaS startup.
   Generous negative space, restrained motion, one metallic accent
   used sparingly, editorial typography with real optical weight.

   Palette:
     --ink        #0A1013  near-black graphite-navy (primary dark)
     --ink-soft   #15222A  secondary dark surface
     --paper      #F2EFE8  warm ivory (background)
     --paper-deep #E7E2D6  recessed panels
     --brass      #9C7F4C  brushed brass (signature accent — used sparingly)
     --brass-dim  #C9B98C  low-emphasis brass (hairlines, ghost text)
     --slate      #52626A  muted secondary text
     --line       #DDD7C8  hairline on paper
     --line-dark  #24333B  hairline on ink
     --white      #FCFBF8
   Type:
     Display: 'Fraunces' — optical-size display serif, light weights, tight tracking
     Body:    'IBM Plex Sans' — quiet, precise
     Mono:    'IBM Plex Mono' — kickers, labels, data only, used with restraint
