The clean-hold: SECONDS, or 'never' — a live notch the operator wants held for the show.
The wire has always carried both spellings and both are real values, so the codec accepts
the union rather than inventing a sentinel number for "never".
limit carries the NUMERIC branch's travel (FBS_HOLD_SECONDS_RANGE, the same span
clampFbsHold enforces) and values carries the one non-numeric member — the shape
fieldTravelOf already reads for a field whose vocabulary rides beside a span. A client
binds both: a numeric field for the seconds, 'never' as a picker option.
