The IN/OUT fields now render h:mm:ss.s timecodes (95.5 shows as 1:35.5) and accept typed input as bare seconds, m:ss, or h:mm:ss. Malformed entries restore the previous value instead of jumping the handle to zero. The center label gains a quiet selected-of-source readout with the source resolution and duration in its tooltip, and the inputs carry ghost hints for the accepted forms.
