Note

Low Risk
Low risk UI-only changes: updates the typing animation to operate on AttributedString and tweaks onboarding layout sizing and test mocks, with minimal impact outside presentation and animation behavior.

Overview
Improves rebranded onboarding text rendering and layout stability. TypingText now animates AttributedString directly (with a String convenience init), and contextual Dax dialog content passes attributed title/message through the typing animation so markdown/bold styling is preserved during reveal.

Also fixes a linear onboarding layout issue by constraining the address bar position picker buttons to a fixed height (min+max), and extends MockOmniBar with long-press callbacks for menu/settings buttons to match updated UI interactions.
