   Fiveta Music — shared site styles
   Used by every page built with tools/build-site.js.

   THEMES
   Colours are tokens. Dark is the base; light is applied when
     - the visitor picked "light"     -> <html data-theme="light">
     - or picked nothing ("auto") and the OS prefers light.
   Never hard-code a text/surface colour in a component — use a token.
