// One graded row: a PASS/FAIL toggle (kind="verdict") or a numeric count input
// (kind="count"), plus a rationale textarea. Used by EventCard, VideoLevelAxes,
// and the Training page's qualification quiz - the single place PASS/FAIL and
// count UI is implemented.
//
// Rationale is always optional (never blocks saving/continuing) - it's
// strongly encouraged on real videos, especially for FAIL, but not required.
