   NEXUS DESIGN TOKENS — the single definition site for colour, type and radius.
   lint-banned.sh enforces that: no other file may hold a colour hex or define a
   --* custom property.

   WHY THIS EXISTS AND WHAT IT REPLACES
   USWDS is kept for COMPONENTS — buttons, forms, accordions, tables, sidenav,
   focus rings, ARIA behaviour. That is the hard, accessible part and it stays.
   Its PALETTE is a public-services palette and is not kept: it reads as a
   government portal because that is what it was designed for.

   ACCESSIBILITY IS NOT THE TRADE-OFF. Every pairing below is measured against
   WCAG 2.x AA (4.5 normal text) on the page background:
     ink        #E8EDF5  16.43:1     accent   #8B9BFF   7.57:1
     ink-2      #A3AFC2   8.71:1     success  #3ECF8E   9.68:1
     ink-3      #727E92   4.70:1     warning  #F5B544  10.65:1
     info       #5CC8E8  10.01:1     danger   #FF7B7B   7.70:1
   For contrast, the previous locked palette FAILED on its own sanctioned navy:
   danger 2.26, warning 2.38, success 2.58, primary 2.01 — all under 4.5.
