What it expects. Any CSV with a team/student column, a challenge column, and the answers — either as a Fields column holding JSON ({"p0":"6","p1":"6"}) or as plain p0, p1, p2… columns. It auto-detects which. If there's a Timestamp or Date column, it dates each attempt and lets you view one day at a time — so a team's Monday run and Wednesday run don't blur together. Nothing is uploaded; this runs entirely in your browser.
