orientation sets the axis, horizontal or vertical, and vertical is a shorthand for it. Pass one of the two, not both.
- A vertical divider needs a parent that lays it out. It takes its height from the line of text it sits in, so a bare <Divider vertical /> between two blocks has no height. Put it in a flex row, a Space or a line of text.
- For the full height of a taller row, give it h-auto inside a flex row that stretches its items. A fixed height breaks when the row grows.
- A vertical divider shows no title. children only render on a horizontal line, and a vertical one logs a warning instead.
- Keep one axis per meaning across a view, so a vertical line does not mean a new section in one panel and something else in the next.
