/* Red Raine Labs - shared stylesheet for SEO landing pages.

   Deliberately EXTERNAL rather than an inline <style> block. The CSP in
   public/_headers whitelists inline styles by sha256, but it also allows
   style-src 'self'. Keeping landing-page CSS in this file means a new landing
   page never needs a new hash and never touches _headers - edit freely.

   Design tokens are copied from index.html so landing pages look native. */
