/* ==========================================================================
   AJA Digital: site.css
   One stylesheet for the whole site. Tokens → base → layout → components
   → pages. Light/dark only, driven by data-theme on <html> (set before
   first paint by the inline script in partials/head.html).

   The "legacy aliases" block maps the token names that demos.css,
   emojiBattle*.css and atelier.css were written against onto the new
   palette, so those feature stylesheets keep working untouched.
