+### 2026-08-15 — checked in the list was not active on the chart
+
+The Drawings checkboxes support bulk operations, but `selectedDrawing` was set
+to null whenever more than one checkbox was checked. Every checked row retained
+the same selected border while no line owned the handles, focus animation, or
+drag target. Duplicated lines had a related path: duplication assigned the new
+id programmatically, but the watcher called `setSelectedLine()` rather than
+`focusLine()`, so the expected glow never ran.
+
+Bulk membership and the active chart drawing are now separate. Checking a row
+adds it to the bulk set and makes it the active drawing; unchecking the active
+row falls back to the most recently selected remaining id. Clicking a row makes
+it the sole selection. The active row has a distinct inset marker, and every
+selection path, including duplication, runs the same focus method. Browser
+coverage checks two rows simultaneously, requires the newest one to own the
+focus and hit polyline, and starts a real pointer drag on that line.
