+/// Covers the per-vehicle selection cards on the Reports tab: once a date
+/// range is picked, every vehicle with a receipted entry in range starts
+/// selected (colored like the "Share" button), tapping one to deselect it
+/// drops it from the total (and, by extension, the generated report) and
+/// reverts its coloring to a plain unselected card, and deselecting every
+/// vehicle shows a distinct "nothing selected" message rather than "no
+/// entries in range". There's deliberately no checkbox — selection state is
+/// conveyed by color alone.
