   Who Is Wilson? — design tokens and base components
   ----------------------------------------------------------------------------
   Extracted from the design canvas (warm technical editorial direction),
   2026-09-03. Values are lifted from the artboards, not rounded to a grid.

   Include in a page head, in this order:

     <link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
     <link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=IBM+Plex+Sans:wght@400;500;600;700&family=IBM+Plex+Serif:wght@600;700&family=IBM+Plex+Mono:wght@400;500&display=swap">
     <link rel="stylesheet" href="/assets/wilson.css">

   The five existing marketing pages still carry their own inline <style> and are
   NOT yet converted — that is the design refresh, done separately. New pages
   should use this file so they are built in the new style once rather than twice.

   If a Content-Security-Policy is ever added to whoiswilson.com it must allow
   fonts.googleapis.com (style-src) and fonts.gstatic.com (font-src), or the
   faces fail silently and everything falls back to the system stack.
