Overview
What the project is designed to do
A privacy-first JavaScript practice lab with a timed ten-question sprint, a searchable thirty-six-question bank, answer review, local progress, and an explainable Study Coach.
The ninety-second sprint and broader practice mode preserve detailed review while progress and a personal leaderboard stay in the browser.
The Study Coach builds deterministic study plans from local performance and can optionally refine wording through Vercel AI Gateway.
Problem
What needed to change
A short timed quiz measured recall but did not support deeper review, repeat practice, explainable study planning, or portable local progress.
Solution
How the release responds
Combine a focused sprint with a searchable practice bank and use transparent performance signals to generate a reviewable study plan.

Architecture
Delivery shape
Static learning pages and local progress use narrow read-only or optional-assistance functions without a shared learner backend.
