/* =========================================================
   EXPORT PANEL  (shared)
   assets/css/components/export-panel.css
   =========================================================
   Styles the shared Export tab UI (export-panel.js): the
   "Export Format" dropdown card + a theme-aware code card
   (header: filename / filename-dropdown + type badge + Copy /
   Download; body: line-numbered, syntax-highlighted code).

   Reuses the website design system tokens (variables.css) and is
   theme-aware via [data-theme] — no new theme. Used by every
   tool's Export tab and later by Studio / Hero.
