      /* Note 1:
      Use 24hr time for gridline names for simplicity

      Note 2: Use "auto" instead of "1fr" for a more compact schedule where height of a slot is not proportional to the session length. Implementing a "compact" shortcode attribute might make sense for this!
      Try 0.5fr for more compact equal rows. I don't quite understand how that works :)
