MithunSrinivas28/Shukan-Discipline-Tracker ? reverse-engineered prompt

Build me a clean, minimalist web app called Shūkan that helps people track discipline through verified study hours and daily commitments.

I want users to be able to sign up, set a daily study goal, log study time only when the app allows it, and see their progress on a personal dashboard with simple stats like total verified hours, weekly activity, best study day, average session length, and how well they matched their plan. Also add a public leaderboard that ranks people by total verified study time and shows their rank, username, days active, total time, and how far they are from the leader.

Keep the design very calm and uncluttered, with muted colors and lots of spacing. Make it feel focused and serious, not gamified. Use the current docs online if you need to, and build it so the study logging feels trustworthy with server side checks.
