Composes with the classes `Box` computes instead of replacing them.

The element it paints.

Gap between children, horizontal and vertical once they wrap.

Makes every child take the same share of the width, whatever its content.

With `grow`, caps each child so a long one cannot push the row past its container. Turn it off only when you want the row to overflow on purpose. Does nothing without `grow`.

Animates the element in when it first scrolls into view. `true` takes the catalogue entrance; an object tunes it — `preset`, `distance`, `spring`, `duration`, `once`, `amount`, `rootMargin` and `index` for a stagger. It lives here rather than on each surface so that `Card`, `Paper`, `GradientBorder`, `Section` and anything else built on `Box` inherit one implementation. Without it `Box` stays a server component; with it the root swaps for a client shell and the children keep rendering on the server. The entrance is a CSS transition, not a JavaScript animation: it is the only motion in the catalogue that fires WHILE the user scrolls, and the compositor should own it.

Wraps children that do not fit onto the next line instead of shrinking them.
