WindowTab picks its layout with two radio buttons that are one setting wearing two labels. A setting row knows one label and one control, so the choice was either two rows that misstate the relationship or a control that holds the whole choice. This is the latter, and it generalises to any small closed set. Segment bounds come from rounded edges rather than a per-segment width. At 201 pixels over two segments the naive form paints two 100.5px halves that land on the same physical column, which leaves a seam in the middle and a gap on the right. Deriving each edge from the run means segment i ends exactly where i+1 starts. Hover keys are derived per segment for the same reason the toggle derives its own: the caller has already spent its id on the enclosing row, and sharing it would tie the row highlight to whichever segment the mouse is over. Disabled is a parameter rather than a BeginDisabled scope because that alpha never reaches draw-list output. The invisible buttons are still submitted while disabled so item count and cursor advance do not change between the two states. MetricsMath gains Center, which is what CenterY always was underneath. Reusing CenterY to centre text horizontally would have read as a bug at every call site.
