  The calendar's slide (AD-12: same-document View Transitions, no framework).
  htmx wraps each calendar swap in `document.startViewTransition`; the view
  marks the new region with `data-sens` — which way the day moved, and whether
  the week moved with it. A later day comes in from the right, an earlier one
  from the left; the arena name and chooser stay put. With no `data-sens`
  (another arena, the same day, a full load) the named parts crossfade.
  Without View Transitions, or with reduced motion asked for, the swap is
  instant.
