A vertically centered showcase layout with icon/title header, body, and footer.

This shell is designed for onboarding or intro-style pages where the main content should stay centered while still allowing scrolling on small screens.

Example:

ShowcaseShell(
  icon: const Icon(Icons.school_outlined),
  title: 'Tattoo',
  subtitle: 'NTUT Course Assistant',
  body: const Text('Feature list goes here'),
  footer: const Text('Powered by NTUT'),
)
