Writing a renderable Lottie for this project

This app renders Lottie with Skia's Skottie module (via canvaskit-wasm), not the JS lottie-web runtime. Follow the rules below and verify the result.

This skill covers the mechanics — the JSON shape Skottie needs. For the craft (timing, easing, choreography, Disney animation principles), see LottieFiles' motion-design skill. Its guidance is in milliseconds; convert to frames with frames = ms / 1000 * fr.

Setting up the project

The deliverable is not just public/lottie.json: the viewer should be set up and the animation should be previewable in the browser. If the player project is missing, create it; if it exists, install/update dependencies as needed, start the dev server, and open the local preview URL for verification.
