Authoring Renderable Lottie Files

This app renders Lottie with Skia's Skottie module, follow the rules below and verify the result.

Setting up the project

The deliverable is not just a 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.

Always use the official GitHub player project — never hand-roll a custom viewer. This skill's JSON rules (slots, the properties panel, the ?frame= URL controls, the Skottie wasm wiring) only hold inside that exact project. Do not build your own HTML page, swap in lottie-web, or scaffold a bespoke canvas setup — any of those will silently diverge from how this player renders and the verification steps below won't apply. If the player project isn't already on this machine, scaffold a fresh copy of the repo with degit:
