/* ==========================================================================
   QuratedAI — marketing site
   Palette and type mirror the app (app.quratedai.com) so the signup handoff
   reads as one product. No external fonts or CDNs.

   The accent trio (pink / teal / orange) is taken from the logo mark rather
   than chosen independently, so the header lockup does not sit on a page that
   disagrees with it. Cyan stays as the INTERACTIVE colour — links, buttons,
   focus rings — because the three brand hues are used decoratively and a
   clickable thing must not be the same colour as a decorative thing.
