/* file: assets/css/walkthrough.css
   Shared by the product pages built as 2 one-screen sections (products/
   ethos.qmd, products/surveyframe.qmd): a hero with the click-through
   walkthrough, then a second section (the request form, or install and
   links). --wt-screen is set by assets/js/walkthrough.js from the real
   navbar height, with a CSS fallback. The brand.scss :root custom
   properties do not reach the compiled bundle (PurgeCSS strips them), so
   the same values are set here. */
