     product." This replaces the deprecated warm "Anthropic Original"
     paper/oxblood ramp, which that spec bans as an anti-pattern.

     Token NAMES are retained (--paper-*, --oxblood-*) because every page
     references them; only their VALUES change — exactly the "override the
     semantic tier, never touch components" theming model the spec defines.
     Despite the legacy names, --paper-* now carries cool slate and
     --oxblood-* now carries Harbor's steel blue. Hexes in comments are the
     source Harbor values; OKLCH is used per the system's color law.
