/* ============================================================
   FNS Shield checkout (/join), 2026-09-25.

   Built from the reviewed concept (design/checkout-concept on PR #8). Every
   colour comes from the site's own tokens in site.css (--ground, --surface,
   --ink, --blue, --good, --band ...), which carry light AND dark values, so
   the old white-on-white dark-mode headings cannot come back. The few tokens
   site.css does not define are added below with the same light / system-dark
   / data-theme pattern.

   Type is deliberately large: 65+ customers, often on a phone, often with a
   technician on the line. Nothing a customer must read is under 17px or
   fainter than --body.
   ============================================================ */
