/* Voltex content pages — the documents search engines and shared links land on.
   Deliberately separate from styles.css: those pages are the trading app, this
   is prose. Sharing a stylesheet would mean every marketing tweak risks the
   order book, and every app change risks the page Google has indexed.

   Same palette and the same three-state theme resolution, so a visitor who
   arrives here from a search and then opens the app does not see two products. */
