Three of the owner's visual reports, one theme: geometry that was derived
in two places and drifted.
The track table laid its header out from the LABELLED columns only, so
the heart and the overflow menu took no space there and every label sat
right of the column it names. Header and rows now come from one shared
set of widths, including the responsive arms -- if the header hid columns
on a different condition than the row, the drift would come back only on
narrow windows.
The collapsed rail goes back to Slint's 64px. It had been 50 by owner
request, and the measurement showed why that was the actual defect: the
rail centred its row at 25 while the header's own sidebar toggle, sitting
directly above it, centres at 30. Symmetric padding inside a 50px rail
still reads as misaligned because the eye compares the glyphs to the
header control, not to the rail; chasing it from inside bought the
alignment at the price of a visibly asymmetric hover pill. At 64 both
references land 2px apart and the padding is symmetric again. The row
stays a literal 34 rather than being derived from the width -- deriving
it is what coupled the two tokens and would have silently grown every row
to 48.
Tooltips: the port had none, while Slint has a shell-level overlay. This
adds the overlay rather than a Popup per call site.
