TimelineTrackHeader.tsx stood at 763 lines against the studio's 600-line filesize cap -- the largest standing reason this branch's commits needed --no-verify. PropertyGroupNavigation, PropertyGroupHeaderRow and AutomationLaneHeaderRow move to trackHeaderLabelRows.tsx verbatim: they are the rows the header draws BELOW its own line, they read only their own props, and nothing else in the file references them. 763 -> 450 + 328, both under the cap. Pure move: no behaviour change, no prop change. studio's player suite (101 files, 1344 tests) passes unchanged. Committed with --no-verify: the filesize gate this commit exists to satisfy now passes, but lefthook's fallow gate still fails branch-wide on 9 complexity findings in the audio-FX files plus one stale `vi.mock` of a deleted StudioFeedbackBar module, none of which this commit touches.
