/* ---- App shell (atlas.html only) -------------------------------------
   The interactive map needs the full remaining viewport height, so
   this page opts out of the normal scrolling content layout: body
   becomes a flex column (sticky nav + the platform's own banner, both
   sized to content, then main filling the rest, then a slim one-line
   footer) instead of the standard hero/multi-column footer used by
   every other page. A fixed height (not min-height) keeps the map's
   own container size stable after load - letting the page grow/scroll
   instead made the map's container resize post-init, which Leaflet
   doesn't track on its own and left blank/grey tiles until a zoom
   forced a recalculation. The side panel scrolls internally instead
   (see #panel in style.css). */
