/* ============================================================
   RATEABLE — landing page
   ------------------------------------------------------------
   Brand palette and typeface are locked to the product app:
     navy #003049 · red #D62828 · orange #F77F00
     gold #FCBF49 · cream #EAE2B7 · canvas #F2F1ED
     Josefin Sans

   Brand hues are used as-is for fills, rules and decoration.
   Where a hue must carry text or a UI boundary it needs more
   contrast than the raw brand value, so semantic tokens below
   step the SAME hue darker. Nothing here introduces a new hue.

   Surfaces are deliberately limited to three — canvas, cream
   and navy — so sections are separated by layout and density
   rather than by near-identical warm tints.
