/* ═══════════════════════════════════════════════════════════════════════════
   SALES ANALYTICS — sa-modal-confirm.css (v3)
   Confirm Mapping Modal (Stage B). Loads after sa-shared.css.

   Owns:
     - Filter input row at the top of the modal body
     - Strong-match section: flat list, vendor pill on each row
     - Weak-match section: expandable, vendor-grouped, dimmer styling
     - Candidate row layout: checkbox + name + meta line
     - Vendor pill on flat strong rows
     - Vendor group headers (weak section only)
     - Empty-filter and empty-list states

   Does NOT own:
     - Modal shell (.sa-modal, .sa-modal-dialog, header/body/footer,
       loading/error/empty states, .sa-modal-intro) — sa-shared.css
     - .sa-btn.ghost-warn for the "no match" button — sa-shared.css

   Modal markup: Pages/SalesAnalytics/Partials/_ConfirmMappingModal.cshtml
   JS handlers: sales-analytics.js → openConfirmModal, renderConfirmPayload,
                                     handleConfirmSave, handleConfirmNoMatch
