/* ============================================================
   SAVAGE DESIGNS — UPSCALE PANEL
   ============================================================

   Styles the INSIDE of the shared upscale panel only. Where the panel sits —
   floating over the board, docked in a sidebar, pushed inline — stays with each
   view, because that is genuinely the view's business and they disagree. Same
   arrangement as css/defringe.css, and the custom properties resolve because
   every page already loads css/styles.css.
