Subject: [PATCH] refactor(login): use semantic design system colors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace hardcoded Tailwind colors with semantic design tokens
  - bg-black → bg-background (main container)
  - bg-gray-900 → bg-card (card background)
  - bg-gray-800 → bg-secondary (input fields)
  - text-white/text-gray-400 → text-foreground/text-muted-foreground
  - bg-blue-600 → bg-primary (login button)
  - text-red-500 → text-destructive (error states)
- Improve form layout with spacing
  - Add space-y-2 between labels and inputs
  - Center CardDescription text
- Fix duplicate CSS rules in globals.css for h1/h2/p
- Update background color to [#151515] for better contrast

Improves maintainability and theme consistency across the application.
