-        2a. Workspace targets about **89% initial zoom** by default to keep small math readable while avoiding extra zoom adjustments.
+        2a. Workspace keeps native image resolution for clarity (especially equations); use in-canvas zoom/pan as needed.
         3. For `Selected Region`, use the **Image Workspace**:
            - Recommended: freehand selection (draw/highlight target); app uses an automatic bounding box around your marks.
            - Optional rectangle selection: use the **Crop** tool.
