Removed all 3 @replit/* Vite plugins from vite.config.ts
Removed Replit devDependencies from package.json
Cleared Replit workspace config (.replit)
Added cross-env for Windows/Mac/Linux compatibility
Result: Project now runs standalone on any system

2. Implemented Beautiful Pastel Color Scheme ✓

Light Theme: Soft pastel blue background, pink cards, cream accents
Dark Theme: Cool slate-blue palette (no more pink!)
Updated CSS variables in client/src/index.css

All UI elements, header text, sidebar labels, and AI responses are translated.

4. Study Mode System ✓

Implemented 4 study modes that affect AI behavior:

Active Learning: AI asks follow-up questions to challenge understanding
Break Mode: AI provides relaxing, pressure-free responses

5. Smart AI Responses ✓

Created client/src/lib/studyModeUtils.ts that:

Generates study-mode-specific greeting messages

Created client/src/contexts/LanguageContext.tsx that:

Shares language and study mode state across components
Auto-saves to localStorage (survives page refresh!)
Provides useLanguage() hook for any component to access settings
Type-safe with full TypeScript support

7. Updated ChatInterface ✓

Complete refactor of client/src/components/ChatInterface.tsx:

Uses language context for real translations
Study mode dropdown with icons
Language selector with all 8 languages
Displays study mode tips
Dynamic AI responses based on mode and language
Messages start empty (users begin conversations)
Beautiful, compact header layout

8. App-Level Setup ✓

Updated client/src/App.tsx:

Wrapped app with LanguageProvider context
All child components now have access to language/study mode

🔄 How Study Mode Affects Responses

Active Learning Mode

Greeting: "Let's dive deep into active learning! Ask me questions and I'll challenge your understanding." Follow-up: "Great! Let me ask you a follow-up question to deepen your understanding."

→ AI acts as a challenging tutor, asking probing questions

Break Mode

Greeting: "Time to relax! Let's take a breather and chat about your studies at a slower pace." Follow-up: "No pressure here. Take your time and let me know what's on your mind."

→ AI is relaxed, supportive, pressure-free

Focused Mode

Greeting: "You're in focused mode. Let's minimize distractions and tackle one concept at a time." Follow-up: "Let's stay focused. Here's the key point you need to understand."

→ AI delivers concise, to-the-point guidance

Review Mode

Greeting: "Great! Let's review what you've learned. I'll help reinforce your knowledge." Follow-up: "Let me quiz you on this concept to make sure you've got it down."

→ AI acts as examiner/reinforcer, testing knowledge

🌍 Language Coverage
