  WHY chart-loading and chart-empty are separate from panel-empty:
  panel-empty is for sections (merchants, products) where there is genuinely
  no data. chart-loading/chart-empty are specific to chart canvases because
  Chart.js has a lifecycle: first we show a spinner, then if data arrives we
  draw the chart, and if data is empty we swap the canvas for a message.
  The canvas MUST be hidden when showing empty state, or Chart.js tries to
  draw on a zero-dimension element and throws.
