## 🚀 Implementation Flow

### For App Pages (dashboard, profile, alerts, tenders)

**Step 1: HTML Head**
```html
<link rel="stylesheet" href="/app.css">
<script src="/auth.js"></script>
```

**Step 2: HTML Body (end)**
```html
<script src="/components/nav.js"></script>
<script src="/components/footer.js"></script>
<script>
  requireAuth();
  // Your page logic here
</script>
```

**Step 3: Use Components**
- Navigation auto-injects at top
- Footer auto-injects at bottom
- Use `.app-container`, `.page-title`, `.grid`, etc. for layout
- Use `.card`, `.btn`, `.badge` classes for components
- Use `fetchWithAuth()` for API calls

### For Landing Pages (index.html, login.html, signup.html)

No changes needed! These pages work independently with existing `styles.css`.
