/*
  KDQC website colours. EVERY colour on the site is set here and nowhere else.
  To change the colour scheme, change the values below; the page CSS (site.css)
  and the inline SVG artwork only use these names.
  Current scheme: "blue" (approved home page design A2r, Oklahoma navy, 2026-10-01).
  The favicon (site/favicon.svg) repeats --navy, --steel and --on-navy as plain hex values: update it too.
  After a change, check text contrast stays at WCAG AA (4.5:1 for body text).
