Pull the baseline-strut height math into a documented computeStrutHeight
util (named constants for the empirical 0.34 / 1.1 factors, with a unit
test) and the per-side native text runs into a SettledText component.
Strut statics move to Tailwind classes with only the height as style:height;
drop the now-redundant style-string $derived bindings.
