A wrapped classic tab strip stopped at the toolbar's left edge on every row,
so the space under the header chips stayed empty and long tabs took a row
each. Once the strip wraps, the toolbar now sits over the strip's top-right
corner and the strip lays its tabs out inline around a float sized to the
toolbar's box (_syncTabStripCorner), so only the rows beside the toolbar stop
short of it and every later row runs the header's full width.
- Wrap is still measured with the toolbar in flow (the corner is dropped
before the measure), so the single-row strip is unchanged.
- A ResizeObserver on the toolbar re-decides wrap + corner and redraws the
lineage routes when a reading or the divider changes its size.
- Falls back to the plain strip when the first tab cannot fit beside the
toolbar (it would otherwise leave an empty band).
- Classic arrangement, desktop, header host only; state/case/ledger, the
sidebar and the tab rail keep their own layouts.
