  * Multi-select category picker for a budget, with a leading "All categories" chip.

  * "All categories" is not one more selectable item — it is the empty selection, which the
  * domain reads as a general budget. Tapping it clears everything; picking any category clears
  * it. That keeps the two states mutually exclusive in the UI, the way they are in the model.
