Anchor

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

The element it paints, and the seam where a router plugs in: pass your framework's link component (`component={NextLink}`) and its own props travel through untouched. It is why the core carries no router dependency.

Opens in a new tab and adds `rel="noopener noreferrer"` in the same move — the two go together so an external target can never reach `window.opener`. Both are spread before the rest, so an explicit `target` or `rel` of your own still wins.

Takes family, size, weight and line height from the parent instead of the `Text` defaults. For text that must sit inside a heading or a button without breaking its type.

Clamps the text to this many lines with an ellipsis. Beats `truncate`, and only applies above zero. Needs a width to work against: inside a flex child, that usually means `miw={0}`.

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.

Cuts the text to a single line with an ellipsis. Ignored when `lines` is set, which does the same thing over several lines. The full text stays in the DOM, so it is still read aloud.

When the underline shows. It is on always because the link has to be tellable from body text without relying on colour; `"hover"` and `"never"` move that job onto something else, and the surrounding design has to provide it.
