mytja/Tarok ? reverse-engineered prompt

Build me a fully open source Tarok app called Palčka, with a mobile friendly frontend for playing the card game and a backend for online matches with friends or random players. It should also work offline against bots, and the game logic should use the custom StockŠkis Tarok engine from this repo so the rules and gameplay feel accurate.

Make the experience polished and easy to use, with clear menus, a way to start a solo game or an online game, and support for multiple languages if possible. Please keep it working well for Android and the web, and make sure the app is ready to run locally with the backend. If you need to check anything about the current setup or the latest docs, look it up online first and then wire it up cleanly.
