Strava Save Activity Morph Path Animation

Upon tapping the 'Save Activity' button, a vibrant orange GPS track path morphs and scales up rapidly to sweep across the viewport, transitioning the interface into a dark celebration screen. On this celebration screen, a stylized orange path continues to animate in the background behind a 'Nice work!' message. The celebration screen then fades away to reveal the final activity details page, complete with a map and a subscription promo card that slides up from the bottom.
