Inline "Learn more" popover anchored to a small info icon.
Use InfoPopover inline with text when a short supplementary explanation benefits from richer content than a tooltip can provide – multiple sentences, inline links, or formatting. It renders a small info icon as the trigger and reveals a 400px-wide popover with the provided content as its body.
If a single sentence is enough, reach for InfoTooltip instead – it’s lighter-weight and more appropriate for purely informational hover/focus content.
When children is omitted, the trigger renders as a 16×16 InfoCircledIcon inside a size-1 IconButton. Pass any element as children to replace the icon (for example a small custom icon). The label prop sets the trigger’s aria-label.
