kuettai/pickle-frontend ? reverse-engineered prompt

Build me a tournament ready pickleball scoring app for tablets and desktop browsers that a referee can use during real matches.

It should have secure login with a simple two step check, then let me load a match and score singles or doubles by tapping the left or right side of the court. Make the scoring follow pickleball rules, including sideout scoring, server rotation, cross court serving, and the right server position for even and odd scores. I also want clear visual feedback, big readable scores, and obvious buttons for manual score fixes when needed.

It needs to work well on iPads, Android tablets, and Windows tablets, with a touch friendly layout and high contrast display for gym lighting. Please make offline support a big focus, so scores are never lost if the network drops, and sync everything automatically when the connection comes back. If you need current browser or auth docs, look them up online. Also include a solid test setup so the important scoring and offline behavior are covered.
