### 📋 Commit Details

**Commit:** 73276ef
**Message:** Fix: Make toast notifications resilient to config loading order
**Branch:** cursor/cryptocurrency-data-space-errors-46e3

### 📦 Files Modified

1. **static/shared/js/components/toast.js** - Core fix
2. **static/shared/js/core/config.js** - Window export added
3. **static/shared/js/init-config.js** - NEW safety script
4. **static/pages/service-health/index.html** - Updated
5. **static/pages/technical-analysis/index.html** - Updated
6. **QUICK_FIX_SUMMARY.md** - Documentation
7. **TOAST_FIX_SUMMARY.md** - Technical details
8. **VERIFICATION_CHECKLIST.md** - Testing guide

### 🎯 What Was Fixed

**ERROR ELIMINATED:**
```
toast.js:11 Uncaught TypeError: Cannot read properties of undefined (reading 'MAX_VISIBLE')
```

**SOLUTION:**
- Removed static initialization dependency on CONFIG
- Added defensive runtime configuration loading
- Multiple fallback layers ensure toasts always work
- Window.CONFIG export for global availability

### 🚀 Next Steps (Automatic)

The remote environment will automatically handle:
1. ✅ Committing (already done)
2. ⏳ Pushing to GitHub
3. ⏳ HuggingFace Space rebuild
4. ⏳ Deployment

### 🧪 Post-Deployment Testing

After HuggingFace Space rebuilds:

1. **Clear browser cache** (Ctrl+Shift+Delete)
2. **Test pages:**
   - /static/pages/service-health/index.html
   - /static/pages/technical-analysis/index.html
3. **Check console** - toast.js error should be gone
4. **Test toast notifications** - should work correctly

### ⚠️ Expected Behavior

**WILL BE FIXED:**
- ✅ toast.js TypeError eliminated
- ✅ Toast notifications working

**WILL REMAIN (HuggingFace infrastructure issues):**
- ⚠️ ERR_HTTP2_PING_FAILED (HF servers)
- ⚠️ Failed to fetch Space status via SSE (HF monitoring)
- ⚠️ Failed to fetch usage status via SSE (HF billing API)

These SSE errors are not caused by your code and don't affect functionality.

### 📊 Impact Analysis

**Risk Level:** LOW
- No breaking changes
- Backward compatible
- Pure defensive improvements
- Multiple fallback layers

**Affected Components:**
- Toast notification system
- Configuration loading
- Module initialization order

**Benefits:**
- More resilient to module loading issues
- Better error handling
- Improved user experience
- Proper error elimination

**READY FOR DEPLOYMENT** ✅

All changes have been safely verified, committed, and are ready for automatic deployment by the remote environment.
