   Saving Grace / Literacy Learner Path — brand stylesheet for the WordPress
   marketing site. Framework-agnostic (no Tailwind): pure CSS custom properties
   + component classes that mirror the React app's landing page exactly, so the
   WordPress content engine looks like one seamless site with the product app.

   Source of truth: artifacts/reading-program/src/index.css (design tokens),
   pages/home.tsx (header/hero), components/SiteFooter.tsx (footer).
   Enqueue this in the theme's functions.php.
