/* Benchmark panel.
   Follows the Data Driven Twin (Sensor Research Studio) design system, same as
   chat.css. Tokens are re-declared on #sci9b-bench because the panel is a fixed
   overlay outside the #sci9b subtree.

   The .bench-btn trigger is styled in chat.css — not here, to keep one owner. */
