   SALES ANALYTICS — sa-modal-vendor-detail.css
   Vendor Item Detail Modal (Stage E). Loads after sa-modal-history.css
   (depends on .sa-history-td-* helpers from that file for the purchase
   history sub-section).

   Owns:
     - Section shells (.sa-vendor-detail-section, titles, range chips)
     - Sales-this-week sub-grid (multi-row, one per mapped POS item)
     - Day cells (empty/today styling)
     - Week totals
     - Empty state for the sales section

   Does NOT own:
     - Modal shell — sa-shared.css
     - Purchase history table inside the modal — uses .sa-history-table*
       and .sa-history-td-* from sa-modal-history.css
     - "View detail →" button that opens this modal — sa-search.css

   Modal markup: Pages/SalesAnalytics/Partials/_VendorItemDetailModal.cshtml
   JS handlers: sales-analytics.js → openVendorItemDetailModal,
                                     renderVendorDetailPayload

   Why depends on sa-modal-history.css: the modal renders its 12-month
   purchase history using the same table styles as the Stage C modal.
   Avoiding duplication of those table rules here matches the v2 handoff
   guidance — duplicate-rule pattern is specifically what we're trying
   to avoid by splitting.
