Accessibility
•
status for info and success, alert for warning and destructive. The actions are ordinary focus stops.
When to use
•
Page-level state that persists until resolved.
Avoid
•
Confirming something that already happened — that is a Toast.
•
More than one banner at a time.
NOTEEvery dimension resolves through Sizing.*(SizeVariant) and the token scales — never a literal. Source: src/eQuantic.UI.Components/Banner.cs.
