Evaluate lightning-navigation vs window.open for external URLs
Real World Scenario
Product team wants LWC to open partner portal links; some open in same tab, others popup-blocked in Safari on iPad.
Expected Answer
• Use NavigationMixin GenerateUrl for internal Salesforce targets only

• Avoid window.open without direct user gesture — triggers popup blockers
• Experience Cloud may restrict external link policies — verify CSP
• Log outbound navigation for compliance if required
• Deep link return URL pattern for mobile apps if applicable
• Document platform differences in admin setup guide
