## 🐛 Bugs Found & Fixed

### Bug #1: URL Validation Bypass ❌ → ✅
**Severity**: HIGH (Security)  
**Found**: Edge case testing  
**Issue**: `https://evil.com/gist.github.com/fake` passed validation  
**Root Cause**: Used `url.includes()` instead of checking actual hostname  
**Fix**: Implemented proper URL parsing with hostname validation  
**Status**: ✅ FIXED

### Bug #2: XSS in Preview ❌ → ✅
**Severity**: CRITICAL (Security)  
**Found**: Deep code analysis  
**Issue**: User content injected without escaping  
**Root Cause**: Used `innerHTML` with raw content  
**Fix**: HTML escaping function + textContent  
**Status**: ✅ FIXED

### Bug #3: No Error States ❌ → ✅
**Severity**: MEDIUM (UX)  
**Found**: Deep code analysis  
**Issue**: User didn't know if button click worked  
**Root Cause**: No loading/success/error states  
**Fix**: Added 3 states with animations  
**Status**: ✅ FIXED

### Bug #4: Regex Special Chars ❌ → ✅
**Severity**: MEDIUM (Reliability)  
**Found**: Deep code analysis  
**Issue**: Template replacement broke with $, ^, [], etc.  
**Root Cause**: Used regex replace  
**Fix**: Changed to split/join  
**Status**: ✅ FIXED

### Bug #5: No Retry Logic ❌ → ✅
**Severity**: MEDIUM (Reliability)  
**Found**: Deep code analysis  
**Issue**: Failed on flaky networks  
**Root Cause**: Single attempt for API calls  
**Fix**: Exponential backoff, 3 retries  
**Status**: ✅ FIXED

### Bug #6: No Rate Limiting ❌ → ✅
**Severity**: LOW (UX/API Abuse)  
**Found**: Deep code analysis  
**Issue**: User could spam click  
**Root Cause**: No cooldown check  
**Fix**: 1-second cooldown + disabled state  
**Status**: ✅ FIXED
