- A horizontal chart's gutter grows to its widest band name, floored at the theme gutter and capped at half the chart; a name past the cap ends in an ellipsis (#10).
- Pagination's previous and next tooltips read i18n (English and zh-CN built in, app catalogs override); `.size(ControlSize)` sizes every control, Sm by default; `.jump()` adds a Go to field (#11).
- NumberInput keys the owner's value as shown: a draft survives a blur, a value set while focused lands when focus leaves, and an echo of its own commit is no new value. A ranged field holds room for its widest bound through `Input::least`.
