/* ===========================================================================
   OrbitQube — shared site design system
   ---------------------------------------------------------------------------
   ONE stylesheet for the whole marketing site. It replaces the large inline
   <style> block that used to be copy-pasted into every page's <head>, and it
   provides the responsive header/nav (with a working mobile menu), the footer,
   the WhatsApp float, and the design tokens + components that the redesigned
   index.html is built from.

   The legacy content pages still load the Tailwind CDN + /assets/js/tw-config.js
   for their utility classes; this file supplies the component classes those
   pages reference (.glass, .grad-cyan, .card-hover, .input-base, .wa-*, etc.)
   so they keep rendering after their inline <style> is removed.
