Durable UI

Durable UI is the practice of making client-side state and interactions resilient. State should survive page reloads, browser sessions, and — where appropriate — be shareable via URL. Interactive elements like dropdowns and modals should be dismissable in the ways users expect (click outside, Escape, backdrop click). Multi-step flows should never lose progress. Durable UI fills the gap for UI preferences, navigation context, and interaction patterns that belong on the client.
