{#
  Steps, sleep and mood against one time axis — the overlay issue #12 asked for.

  🔴 EACH LINE IS SCALED TO ITS OWN RANGE. Steps run to ~20,000 and sleep to ~8; on one
  shared axis the sleep line is a flat smear along the floor and the chart says nothing.
  The macro prints the sentence that makes that readable rather than misleading: only the
  TIME axis is shared, and the gap between two lines means nothing.

  🔴 THE AXIS ENDS AT THE LAST DAY THE EXPORT COVERED, NOT TODAY. Apple delivers a day's
  numbers overnight, so today is empty until tomorrow — and a chart that runs to today
  would show every metric falling off a cliff at the right-hand edge, every single day.
