   page-detail-donut-chart.css
   The pie-chart "donut panel" used on detail pages that show a
   per-product breakdown chart inside the white card chrome:

     • Member state detail   "Key Import Products" tab
     • Commodity detail      "Producers" tab

   Changing the donut layout, header type, or legend style HERE
   updates both pages at once. The card chrome itself
   (background, border, radius-lg, soft shadow, overflow:hidden)
   stays shared with .cc-table-card / .table-section in table.css
   so all three tab-content surfaces read as the same white-card
   system; this file only carries the donut-specific layout +
   typography on top.
