feat: Brilion landing page redesign (Sarvam-inspired)

[akashmahlaz]

🎨 Landing Page Redesign

Full redesign of src/routes/landing.tsx inspired by sarvam.ai design language.

---

🔴 Before (old landing.tsx)

• Generic dark theme with bg-background
• Shadcn <Button> and <Card> components
• Plain hero with a blur glow effect
• 6 icon-based feature cards
• Simple 3-step "how it works"
• Name was MyAI not Brilion

🟢 After (new landing.tsx)

• Warm gradient hero — orange → peach → lavender → light blue (exact Sarvam feel)
• Playfair Display serif for all headlines
• Animated orange/gradient announcement bar at top
• Clean light layout — #fafaf8 bg, white sections, thin #e8e8e4 borders
• Uppercase pill nav — same style as Sarvam
• Numbered pillar cards (01, 02, 03)
• 6 use case cards with real WhatsApp example prompts per vertical
• How it works (4 steps) + integrations grid (12 apps)
• Chat demo window with macOS chrome (red/yellow/green dots)
• Dark CTA with email waitlist input
• Multi-column dark footer
• All Brilion-branded (not MyAI)
• No Shadcn Card/Button dependencies — pure Tailwind

Restore Route export in landing route module

This change deletes all contents of src/routes/landing.tsx, so the file no longer exports Route; however, the generated router (src/routeTree.gen.ts) still imports Route from this module for /landing, which causes the app to fail to load with a missing export error as soon as the router module is evaluated. This is a release-blocking regression because it breaks startup in any environment that includes the generated route tree.
