## 3. Code Proof Snippets

### 3.1 Fake 3D RBS object — pure CSS (no Three.js, no asset bytes)
```jsx
<div
    className="relative w-52 h-52 xl:w-60 xl:h-60 mx-auto mb-10 z-10 animate-login-float"
    style={{ perspective: "1000px", transformStyle: "preserve-3d" }}
    aria-hidden="true"
>
    {/* Back depth shadow */}
    <div className="absolute inset-0 bg-sky-500/35 blur-2xl translate-y-12" />
    {/* 3 nested gradient layers offset by translateZ -30 / -15 / 0 */}
    <div className="absolute inset-0 rounded-2xl bg-gradient-to-br from-blue-950 to-blue-900 border border-white/10" style={{ transform: "translateZ(-30px) translateX(8px) translateY(8px)" }} />
    <div className="absolute inset-0 rounded-2xl bg-gradient-to-br from-blue-800 to-blue-950 border border-white/10" style={{ transform: "translateZ(-15px) translateX(4px) translateY(4px)" }} />
    <div className="absolute inset-0 rounded-2xl bg-gradient-to-br from-blue-500 via-blue-700 to-blue-900 border border-white/20 backdrop-blur-md flex flex-col items-center justify-center"
        style={{
            boxShadow: "inset 0 0 40px rgba(255,255,255,0.18), 20px 20px 40px rgba(0,0,0,0.6), 0 0 60px rgba(56,189,248,0.35)",
            transform: "rotateX(20deg) rotateY(-20deg)",
        }}
    >
        <div className="text-5xl xl:text-6xl font-black text-white tracking-tighter" style={{ textShadow: "0 0 15px rgba(255,255,255,0.5), 0 0 30px rgba(56,189,248,0.6)", transform: "translateZ(30px)" }}>RBS</div>
    </div>
</div>
```

### 3.2 New Tailwind keyframes
```js
// tailwind.config.js
keyframes: {
    'login-float': { '0%, 100%': { transform: 'translateY(0) rotateX(20deg) rotateY(-20deg)' }, '50%': { transform: 'translateY(-15px) rotateX(22deg) rotateY(-18deg)' } },
    'login-glow':  { '0%, 100%': { opacity: '0.5', transform: 'scale(1)' }, '50%': { opacity: '0.85', transform: 'scale(1.05)' } },
    'login-fade-in-up': { '0%': { opacity: '0', transform: 'translateY(15px)' }, '100%': { opacity: '1', transform: 'translateY(0)' } }
}
```

### 3.3 Glass feature card
```jsx
<div className="group p-4 rounded-xl bg-white/[0.03] hover:bg-white/[0.06] border border-white/10 hover:border-sky-400/40 backdrop-blur-md transition-all duration-300 hover:-translate-y-1 hover:shadow-[0_8px_30px_rgba(56,189,248,0.22)]">
```

### 3.4 Auth logic — 100% preserved
The `submit`, `errorMessage` mapping, `useEffect` for `?skip-tour=1`, `useAuth().login`, `Navigate` redirect, brute-force lockout message handling, password show/hide, validation `touched` state, `forgot-password` link — ALL untouched.

## 4. Acceptance Criteria — design_guidelines.json

| Criterion | Status |
|-----------|--------|
| No external fonts loaded (system-ui only) | ✅ |
| No 3D libraries (Three.js etc.) | ✅ pure CSS |
| Left panel uses strict white/slate/emerald hierarchy | ✅ |
| Right panel grid + background glows render via standard CSS | ✅ |
| 3D RBS object via CSS transforms + nested shadows | ✅ |
| Status indicator defaults to online with correct `data-testid="system-status-indicator"` | ✅ |
| 8 feature cards with sky-blue glow on hover + upward lift | ✅ |
| Right panel hidden under 1024px | ✅ `hidden lg:flex` |
| Auth flow preserved (login form, error handling, skip-tour) | ✅ |

---

## 5. Test Evidence

### 5.1 UI screenshot at 1920×1080 (`/tmp/login_desktop.png`)
- Left panel + right hero rendered side-by-side
- All 8 feature cards visible
- Fake 3D cube floating with glow
- Status pill shows ONLINE

### 5.2 Live auth flow regression
- Email `regalmarketing2024@gmail.com` + password → click "Sign In Securely"
- URL transitions to `https://offline-billing-pro-2.preview.emergentagent.com/`
- Dashboard renders → confirms login still works

### 5.3 Webpack
```
webpack compiled with 15 warnings  ← (all are pre-existing zxing source-map warnings; non-blocking)
```

### 5.4 testids confirmed present (1 each)
```
system-status-indicator: 1
login-hero-panel: 1
login-hero-features children: 8
login-hero-tagline: 1
login-email-input, login-password-input, login-submit-button, login-show-password, login-forgot-link, login-form, login-screen: 1 each
```

| Rule | Status |
|------|--------|
| 1. Multi-user | ✅ login is per-user from day one |

| 4. Security first | ✅ JWT/cookie auth preserved; brute-force lockout text preserved |
| 5. Fraud prevention | ✅ Login activity already audited by AuthContext |

| 8. Performance first | ✅ Zero external assets, pure CSS animations, lighthouse-friendly |
| 9. Data safety | N/A |
| 10. Admin control | N/A |
| 11. AI development rule | ✅ design-agent blueprint used, production-optimised |

## 7. Restrictions Honoured

| Restriction | Status |
|-------------|--------|
| No competitor logos | ✅ |
| No "better than" claims | ✅ |
| No Tally / Vyapar / Busy / Marg references in user-facing text | ✅ (OnboardingTour fixed too) |

**Status: PASS** — SPEC 1 (Premium Login Hero) implementation verified end-to-end.
