/*
 * Calendar: month grid, agenda, toolbar, filters, day popover, print.
 *
 * Month grid structure: one nested CSS Grid per week row rather than a single
 * 42-cell grid. That is what makes multi-day spanning trivial — a bar is just
 * `grid-column: 3 / span 4` — instead of absolutely positioning over cells and
 * recomputing pixel offsets on resize.
 *
 * Row 1 of each week holds the date numbers; rows 2..n are event lanes.
 * Day backgrounds span every row at z-index 0 so today/weekend/out-of-month
 * tinting needs no second stacking layer.
