Callout
An emphasised aside with a variant accent and a derived uppercase label.
<arc-callout> Callout was removed in v4.0.0. It is not published, and
<arc-callout> no longer resolves to anything. This page is here so the link
still answers.
Why
Merged into arc-alert, which gained `tip`, an `icon` slot and a `live` prop to absorb it.
Use instead
- Alert `variant` carries over, `tip` included. The derived uppercase label has no equivalent — pass `heading` if you want one.
