OctaveSpanEvent class
One staff-scoped activation of an OctaveMark on the musical timeline.
onset is measured in whole notes from the start of the staff — the same
absolute clock PositionedElement.onset carries, so LayoutEngine (which
builds the timeline from the model, before anything is positioned) and
StaffRenderer (which rebuilds it from a positioned list) produce
identical events for the same music.
A producer using a per-measure clock instead would still be self-consistent: OctaveSpanTimeline only ever compares onsets of events sharing the same measureIndex, and within one bar the two conventions differ by a constant. Do not MIX the two in one timeline.
