+- **Task 1.09: Address Book — vCard Export + Registratura Reverse Lookup** ✅
+  - Created `src/modules/address-book/services/vcard-export.ts` — generates vCard 3.0 (`.vcf`) with all contact fields
+  - Added Download icon button on contact card hover → triggers `.vcf` file download
+  - Added FileText (detail) icon button → opens `ContactDetailDialog`
+  - `ContactDetailDialog` shows full contact info, contact persons, notes, and scrollable Registratura table
+  - Registratura reverse lookup uses `allEntries` (bypasses active filters) and matches `senderContactId` or `recipientContactId`
+  - Build passes zero errors
