+    title: OctoPrint height widget uses clean template sensor, not raw REST sensor
+    decision: OctoPrint height widget must point at sensor.octoprint_height_progress_clean. Do
+      not delete this template sensor or repoint the widget to the raw REST sensor — its
+      float32 total attribute and display_precision 0 default round the widget display.
+    rationale: Widget shows state + total attribute in one tile. The REST sensor's total
+      attribute is a float32 artifact (75.5999984741211) from the DisplayLayerProgress
+      plugin JSON and cannot be transformed at source; its display_precision 0 default
+      rounds the widget current value up (85.6 -> 86). The YAML template sensor
+      (configuration.yaml template block) re-exposes state and total rounded to 1 decimal,
+      with its own display_precision set to 1.
