Claim: Same-document View Transitions reached Baseline Newly Available on October 14, 2025, when Firefox 144 shipped support — joining Chrome 111+, Edge 111+, Safari 18+.

Verbatim (web.dev, Oct 14, 2025): "this web feature is now available in all three major browser engines, and is Baseline Newly available as of October 14, 2025."

Confidence: Verified.

Pattern: document.startViewTransition() + view-transition-name CSS property. For Astro sites with internal navigation, adopt as default. For React SPAs, pair with useViewTransition hook (React 19).

Use case: thumbnail → full-image morph (view-transition-name: product-image), SPA-style page transitions, modal open/close. Stop reaching for Framer Motion or GSAP for these patterns on marketing sites.
