   prismo.cz — marketing site
   ---------------------------------------------------------------------------
   Palette and typeface are the app's (frontend/src/index.css), so the site
   and the product read as one thing: blue = us / primary action / margin,
   teal = done / fine, amber = something still to fill in. Light only.

   The page is mostly large type on white. No eyebrow labels, no card grids,
   no dark slabs: a section is a heading, a sentence or two, and at most one
   picture that carries the point.
