+- Live browser validation caught and fixed cramped map-result metric cells;

+Live operational proof:
+- Tower deployed commit `d22abe8` with AI extras enabled. The all-in-one
+  runtime became healthy, PostGIS 3.6 passed, Alembic reached `202607150001`,
+  and the new table exposed 13 columns plus six expected indexes.
+- Quality check `acaca138-dbb9-4498-ae53-d0732b6270e3` returned 206 persisted
+  evidence geometries in 338 ms with zero unresolved ids. All 72 reviewable

+- A new browser-driven 35.57 ha Mol rectangle acquired the official orthophoto,

+  `087d2b6a-6d3c-4508-ab1e-da49734097c2` at IoU `0.25`.
+- The live run produced 100 candidates, 73 matches, precision `0.73`, recall
+  `0.4965986395`, F1 `0.5910931174`, mean IoU `0.5361610234`, 27 false
+  positives and 74 false negatives. The UI showed these values as measured
+  candidates and retained the explicit `controle vereist` source warning.
+- Browser audits at 1280x720 and 3440x1440 had no console warnings/errors or
+  horizontal overflow. The review queue rendered 50 paginated rows; the
+  ultrawide map used about 2,410 px. A final compact-metric fix was queued after
+  the 1280 px screenshot exposed cramped six-column labels.
