   styles.css — the site's complete design system.

   One stylesheet, organized top to bottom roughly in the order the page is
   read: design tokens, then the shell (nav), the hero, the agent console, and
   finally the content sections. Colors are centralized as CSS custom properties
   in :root, so re-theming means editing one block.
