Animated Tab Switcher with the View Transitions API (No Library)

A tab switcher where the active pill slides and the content cross-fades using the native View Transitions API (document.startViewTransition()) - no animation library, no manual transform or opacity choreography. Falls back to an instant, fully functional tab switch in browsers that don't support the API yet. Copy the HTML, CSS and JS below and drop it into any project.
