   Predictive Purpose — Self-Assessment Diagnostic
   Served at tool.neilcatton.com, framed by the live site's nav and footer.

   Section 1 — SITE CHROME: copied from neilcatton-website/index.html
   (palette, base type, nav, dropdown, page header, buttons, footer,
   keyframes, responsive rules) so nav/footer/header render identically
   to the live site.

   Section 2 — TOOL: the diagnostic itself, restyled onto the site's own
   tokens (ink / ink-mid / ink-light / paper / paper-mid / accent /
   accent-mid / rule; Playfair Display for headings, Source Sans 3 for
   body and labels).
