Shadow-sama287/space-A ? reverse-engineered prompt

Build me a clean web app for DSA spaced repetition revision, like an Anki style tracker for interview prep.

It should come with a huge preloaded list of DSA problems from the Striver SDE sheet and A2Z sheet, let me browse them in an explorer, open the original problem link with a Solve button, then come back and mark how well I remembered it with a simple 0 to 3 review score. Based on that score, the app should automatically schedule the next review using the SM 2 spaced repetition rules, and show me only the questions that are due today.

I want a very minimal monochrome look, almost brutalist, with no distracting UI. Also include progress tracking like a daily streak, a 28 day heatmap, a 7 day forecast of upcoming reviews, and topic wise progress bars. If you need to, look up current docs online for anything unclear, but keep the experience simple and focused on revision.
