   Source aesthetic: andreyg.com (light, monospace, gold accent)

   Default palette is LIGHT (matches andreyg.com). A project that
   wants a dark skin (e.g. solar-system) overrides the palette
   tokens in its own :root block loaded after this file — no need
   to fork this file.

   Keep identical copies in:
     - andreyg-com/public/theme.css
     - lang-detect-web/src/main/resources/static/theme.css
