hamedzurat/stride — reverse-engineered prompt

Build me a real time web app for academic assessments and competitive programming called Stride. I want teachers to be able to create programming problems, including using AI to draft full problem statements, edge case tests, and nicely formatted descriptions. The editor should feel polished and support rich text plus math and LaTeX for more technical questions.

Students should be able to open problems, write code, submit solutions, and have their code compiled and run against test cases through Judge0. Scores, submissions, and problem updates should sync live across all open sessions without needing refresh. Please make the interface modern, clean, responsive, and accessible, with a dashboard style experience for classes, activities, and assessments.

Use the Svelte app setup in this repo and wire it up with the real time backend already implied here. It should run locally with Bun and use env vars for the backend, OpenAI, and Judge0 keys. If anything is unclear, look up the current docs online and finish it end to end so I can clone it, add keys, and start using it.
