+- Result counts in tab labels: "Active (6)" / "Sold (3)"
+- Condition badges on raw listing cards using detectedCondition from API
+- Price outlier warnings (flagPriceOutliers applied in API pipeline)
+- GRADED badge for slab listings in detail panel
+- Inline PSA stats in Prices tab with gem progress bar
+- Price chart x-axis date labels
+- Arbitrage "Best Price" chip and savings summary

+- Moved lib/demo.js to lib/data/, lib/output.js to lib/search/
+- Umbreon demo data: added detectedCondition (NM/LP) based on AI grades
+- Detail panel: prefer detectedCondition over "Ungraded"
+- Consistent shipping display with green "Free shipping"
+- CI: unit + smoke run in parallel, test gate job, removed duplicate dev push trigger
