/* ==========================================================================
   Nevoura — Product Page Theme Showcase
   Apple-style: neutral, quiet, generous whitespace, system typography.
   No gold/decorative palette — text is near-black/gray, the only colour is
   the site's own --nv-accent token, used sparingly (active dot only).
   Shown below the product summary; content is fetched live per selected
   Theme (see assets/js/product-options.js).
