/* humaid landing — warm editorial design.
   Cream paper background, terracotta accent, muted blue for water, deep
   ink-black text. Serifs for headings to lean on the heritage angle; sans
   for everything else. No external fonts — system stack only.

   This file is NOT processed by Tailwind. It ships verbatim as the landing's
   stylesheet. The chat app uses /static/styles.css (Tailwind output). */
