Study Mode 167 - Minimal MVP

This is a lightweight single-page implementation (HTML/CSS/JS) for Study Mode 167.

Files:

• index.html — main page
• styles.css — styling (blue theme)
• app.js — application logic (localStorage persistence)

Features implemented:

• Focus Mode: Pomodoro timer (25/50 min), single-task enforcement, auto-suggest Reflection Mode at session end
• Memory Mode: Add flashcards, SRS with simple intervals (1,3,7,14 days), active recall workflow
• Deep Mode: Feynman analysis helper and a simple mindmap builder
• Reflection Mode: Save reflections and show weekly summary

How to run:

1. Place files in a folder and open index.html in a browser.
2. All data is stored in browser localStorage.

Notes & next steps:

• This is an MVP. For production, consider server-side storage, user accounts, notifications, and richer mindmap visuals.
