Build me a Snapchat style web app that feels polished and playful, with the camera opening in the browser and asking for webcam access. I want users to be able to see themselves live, take snaps, apply fun face filters, and browse a simple snap map view if a map key is available. Make it feel close to a native mobile app when added to the home screen, and keep the UI clean and modern with smooth transitions.

Use a React app with global state so the camera, filters, and map data stay in sync, and make sure the code is written in TypeScript. Style it with SASS and structure it so each feature lives in its own neat folder. Include a reusable component library and a few Storybook examples for the main UI pieces. Also add basic tests for important flows and end to end coverage for the main user journey. If you need current docs for any browser or camera API details, look them up online first.
