/**
 * charte.css — Ravivo Labs brand skin for the WordPress account page.
 *
 * Replicates the "Vintage Chaleureux" design system from the React studio:
 *   - Variables: src/styles/global.css → :root
 *   - Tokens:    tailwind.config.js (colors, shadows, radius, fonts)
 *   - Components: SiteHeader.tsx + SiteFooter.tsx layout logic
 *
 * Google Fonts are loaded via wp_enqueue_style() in ravivo-proxy.php.
 * Font families declared here assume the stylesheet is already loaded:
 *   - Fraunces (display / serif)
 *   - DM Sans  (body / sans-serif)
 *
 * Mobile-first: 375px base → 900px desktop breakpoint (matches studio).
 *
 * @package ravivo
