+## v20260103-20-reports-export-html-open-new-tab
+
+- Fixed report export logic so the selected output format is always respected.
+- Ensured the export URL explicitly includes the chosen format parameter (CSV, PDF, HTML).
+- Changed HTML report handling to open in a new browser tab instead of triggering a file download.
+- Enabled proper inline rendering of HTML reports to support graphical preview and layout validation.
