/* China Shop — futuristic storefront theme.
   SYSTEM THEME BY DEFAULT (TB-THEME pattern): light tokens are the :root
   default under a light OS, dark tokens apply via
   @media (prefers-color-scheme: dark) unless the visitor picked light, and
   via [data-theme="dark"] when explicitly chosen. The toggle (app.js)
   cycles System -> Light -> Dark and persists in localStorage "cs-theme". */
