On-device review follow-ups:
- Month widget grid is now tappable. Day numbers open that day and event
bars open the event's detail, both rooted in the month view so back
returns to the grid. Previously only the prev/next/today header
controls responded — the grid cells were never clickable.
- Pill/drawer view switches now build a visit history instead of
collapsing to the default view. Back retraces the views you moved
through (a not-yet-visited view is pushed; revisiting one collapses the
loop back to it), down to the default, then exits. Widget launches
still reset to their own view context.
Refs #1, #2 (reported by @devinside).
