Purpose
The position-aware control for the page-level Board card. grid-card resolves to
after-position-card, which renders inside each position card and supplies that
position as context — so position.activity reads and the card is drawn once per
role rather than once for the page.
Capabilities
Summarize activity for the position the card belongs to.
Show that activity across today, the last 7 days and the previous month.
