/* ==========================================================================
   Transform 75 by Sikora — marketing site
   --------------------------------------------------------------------------
   The palette is lifted from the app's default Sunset Orange theme so the
   site and the product are recognisably the same thing:

     primary   rgb(1.00, 0.58, 0.00)  #FF9400   AppTheme.sunset.primaryColor
     secondary rgb(0.85, 0.45, 0.00)  #D97300   AppTheme.sunset.secondaryColor
     bg stops  #0F0A08 → #2B170A               AppTheme.sunset.backgroundStops

   Ink levels mirror SurfaceDesign.Ink (1.0 / 0.78 / 0.52 / 0.48) and the card
   surface mirrors AppSurfaceStyle: a lifted panel with an accent wash, a lit
   top hairline and a real shadow — never an outline. See CLAUDE.md §2.
