   RESIZABLE SIDE PANELS
   Shared by #task-drawer (editable) and #watch-drawer (read-only
   preview). A slim control bar (width presets + floating ✕) sits
   above each panel's own header, and a thin drag handle runs down
   the left edge — dragging left grows the panel since it's anchored
   to the right of the viewport.
