Overdue tasks sorted identically by date and urgency because
due dates happened to correlate with interval length. Shifting
"Review finances" earlier breaks the correlation.

Headless Chrome skips rendering beyond the viewport, so
selector-based calendar screenshots were either too tall or
blank. Temporarily resizing the viewport forces a full render,
then an explicit area clip captures just the column.
