Hold Shift while dragging to brush a region, or click a point. A
committed brush enables the form; the optional marimo bridge
exchanges JSON-safe state with Python on
http://127.0.0.1:8765.
The page listens to the named interval and point selections, then
writes saved annotations back to the embed's named dataset. Add
?bridge=1 to connect this page to the notebook example
while keeping the browser UI in control.
Brush a region to enable the annotation form.
