   Stylesheet — colors are CSS variables below, sampled from
   the official HIPA logo (navy #0D3B48, coral #FF5931).
   A light theme (default) and dark theme are both defined;
   js/script.js toggles [data-theme="dark"] on <html> and
   swaps the header icon to match. Headings use Fraunces
   (serif), body text uses Inter, both loaded from Google
   Fonts in the page head with system-font fallbacks below.
