How do you use Salesforce Flow to create a guided, accessible UX experience?

Screen Flows are the primary tool for guided UX in Salesforce. Key design considerations:

1. Navigation: Use Back and Next buttons thoughtfully — avoid forcing users to restart if they navigate back. Store user inputs in flow variables so data is preserved.
2. Progress indicator: Enable the flow progress indicator (available in auto-layout and free-form) to show users where they are in a multi-step process — addresses Nielsen's Heuristic 1.
3. Auto-layout: Preferred for maintainability and clarity; elements are arranged in a single connector path making logic easier to follow.
4. Conditional sections: Use visibility rules on screen components to show or hide fields without creating separate screens, reducing cognitive load.
5. Accessibility: Flow screen components inherit SLDS accessibility. Custom LWC components embedded in flows must include proper ARIA attributes.
6. Error handling: Use Fault connectors and custom error messages to explain failures in user-friendly language. Avoid generic "An error occurred" messages.
