Class FlowPaletteComponent

Palette sidebar for creating new nodes — click it or drag it.

Foblex's fExternalItem directive supplies drag-to-canvas placement, which is the precise gesture when the author cares where the box lands. It is not, however, the only gesture people try: a palette that looks like a list of buttons gets clicked, and for a long time a click here produced nothing at all — the item was a bare <div> with no click binding, so the interaction never even reached the editor. The entry is now a real <button>, which restores the click, the keyboard (Enter/Space), and the focus ring for free, and emits NodeTypeActivated.

Both gestures converge on the same NodeAdded event in FlowEditorComponent — one code path, so a host that handles the drop automatically handles the click.
