Optionalchildren?: ReactNodeExtra action(s) between the primary button and the secondary link (rare).
The emblem glyph, e.g. <AlertIcon className="size-8" />.
OptionalonPrimary?: () => voidOptionalonSecondary?: () => voidOptionalprimaryLabel?: stringPrimary CTA; omit to render no button (e.g. an unrecoverable stop).
OptionalsecondaryLabel?: stringA quiet text link under the primary, e.g. "Contact support".
Optionaltone?: FullStopTone
The whole-screen full-stop surface — the escalated end of the error system, shown when a view can't function and it takes over the content area. Weightier than an inline alert on purpose: it fills the space it's dropped into, centers, carries a haloed emblem and a faint brand mark, and leads with one primary action plus a quiet support link.
