/* ESFD EMS shift calendar — shared styles for the volunteer and officer views.
   Deliberately mirrors the printed Wiki Calendar the chief is using today:
   a 7-column month grid with sub-boxes per shift block. Below 900px the grid
   collapses to a stacked day list, because most volunteers will open this on a
   phone. Print styles keep the desktop grid so it can still go on the wall. */
