- updateMode() now subscribes to keydown, keyup AND mousemove so the
body class stays in sync regardless of where focus is (mirrors the
pattern from the working modifier-click demo)
- cursor: copy replaces crosshair (matches copy-affordance semantics)
- figure, h2–h4 and [data-widget-name] elements get a dashed indigo
outline + subtle background tint when shift is held, so the user
can see which elements are annotatable before clicking
