   KarenFerrero.com — landing page ("model card") styles
   ---------------------------------------------------------
   The landing page reads like an AI model card: a clean
   documentation page with one highlighter-yellow accent.
   Colors and fonts live in :root below; change them once here.
   (The hidden inner pages use styles.css, not this file.)
