/* Kazitel website: W3.CSS 5 + a W3 colour theme does most of the work. This file adds the page frame
   (white sheet on a hatched grey background, header, menu bar), the type, and the red sign-up button.
   Brand colour comes from the W3 theme via --kz-brand (set in site/layout.blade.php).
   Your own styling goes in public/css/site-custom.css (loaded last; updates never touch it). */
