    <!-- Disable browser translation site-wide. Google Translate / Chrome
         / Edge / Yandex rewrite text nodes after React has rendered;
         React's next reconciliation then crashes with
         `insertBefore … is not a child of this node` (mostly inside
         numeric / chip components like ProfitAndPerc, MetricCard, the
         drawer profit panels). Trading data shouldn't be machine
         translated anyway — tickers, USDT, BTC, percentages, etc. all
         lose meaning. Matches what we did at the HTML level in the
         legacy dashboard. -->

         as hundreds of "duplicate" indexable URLs. The SPA serves this same
