- Guard canvasScale before dividing by it in outerCardInset, matching
calculateBoardUiScale's own fallback.
- Fix containerContentScale's vertical fit ratio for scrollable
containers: it was derived from the full (all-rows) content height,
which drifts toward 1 as more rows are added regardless of the fixed
inset, under-scaling relative to what the visible viewport actually
needs and clipping the bottom of the visible rows. Use
viewportHeight/viewportRowCount instead, which describe the real
visible card size in both the scrollable and non-scrollable case.
