+
+- Background maintains lightweight per‑tab state `{ url, isArchive, itemsCount, filteredCount }`.
+- Default: on archive.org `/download/*` tabs, badge shows total item count; on other tabs, it is blank.
+- When the popup filters change, it sends `popup.filteredCount`, and the badge shows that filtered count for the active tab.
+- Badge updates on tab activation and URL changes; quick actions (copy/send) update only the current tab’s badge.
