- Page the session grid at 12 cards per page: a filter change re-anchors
the pager at the first page, and clamping keeps a shrunken list's view
in range instead of showing a blank page.
- Redesign the session cards: 3 columns, a project pill, a first-active-
day line under the relative time, wrap-clamped titles with uniform row
heights, a turns-and-steps lead figure, and the cost label shortened
to 费用/Cost.
- Restack the insight band as one folding row — the KPI 2x2 block beside
the activity heatmap — and drop the aggregate composition card with
its now-unused fold, keys, and styles.
