/* PRNeuron website.

   The same neo-brutalist language as the app (frontend/src/index.css):
   warm paper, ink outlines, flat saturated fills, hard offset shadows.
   Someone moving from the website into the product should not feel the
   floor change. Tokens are copied rather than shared because the site is
   a separate static deploy with no build step. */
