Paging between months, weeks and days looked rough, and the transition was the
reason: a full-width slide with no fade at all. AnimatedContent stacks the two
pages and both were fully opaque, so what you saw was one grid racing across
another and clipping at the viewport edge — the movement was carrying the entire
transition, over the longest distance available.
It is now M3's shared-axis X. The offset only hints the direction — a fifth of
the width — while a cross-fade does the swapping, position springs and opacity
eases, and the size transform no longer clips. All three calendar views share
this transition, so all three settle.
Also lifts the month view's swipe threshold from 6dp to the 24dp the week and
day views already used. Six is inside the distance a tap wanders, so brushing
the grid turned the page — which reads as the animation firing at random rather
than as an over-eager gesture.
