Mirrors the orders totals exactly: /stats (offers) + /list-totals (issued + received invoices) endpoints sum each doc's total per currency across the active filter (reusing extracted where-builders so they stay in sync with the lists), rendered as the identical 'Celkem: …' block via the shared formatMultiCurrency. Existing invoice/received KPI stats untouched. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
