   • Colours / brand  → edit the :root block (dark) and
     [data-theme="light"] block (light) below.
   • Fonts            → swap the family names in :root AND
     update the <link> tags in index.html.
   • Max content width, nav height, section spacing
                      → the sizing vars in :root.
   • No colour hex values appear outside these two blocks.
