The grip's `-m-1 p-1` pair cancelled on three sides only: `.dui-frame-head`
sets `margin-top: -0.5rem` unlayered in core.css, which beats a Tailwind
utility, so the padding above went uncancelled and the title dropped 4px the
moment the editor opened. The grip's geometry moves into core.css beside the
head's own half step, where one declaration cancels all four sides.
Slider tick labels were placed in percent with nothing measured, so five
four-character labels crowded on a tile narrower than the default four
columns. A ResizeObserver on the slider reports its width and every Nth label
is kept, N a divisor of the interval count so the first and last stay.
