def init(_opts) = Model.new(count: 0)

def update(model, event)
  case event
  in Event::Widget[type: :click, id: "increment"]
    model.with(count: model.count + 1)
  else
    model
  end
end

def view(model)
  window("main", title: "Counter") do
    column(padding: 16, spacing: 8) do
      text("count", "Count: #{model.count}")
