/* =========================================================================
   Plannr marketing site
   -------------------------------------------------------------------------
   One stylesheet, no framework, no build step. Serves index.html plus the
   shared chrome (nav / footer / policy body) on privacy.html + terms.html.

   Palette comes straight from the app: navy #002E61 and gold #FDB814 are
   sampled from the 1024px app icon; the wave blue #3D7EDE from the sign-in
   screen. The marketing surface is a warm "paper" so the syllabus reads as
   paper, the story reads as editorial, and the real (dark) product UI reads
   as product.
