- Calendar: the 'Color the calendar by' selector shrinks to its tabs and sits
centered over the month grid beyond phone widths (scoped under .metric-block
so the Compare basis toggle keeps filling its param cell).
- Calendar: the category-totals strip widens to 960px and centers in the
content column.
- Weekly: the chart metric switch likewise shrinks to its tabs and centers
over the trend chart. Phone layouts (full-width 4-per-row toggles) are
untouched.
