Bits of .NET

@layer reset, base, components, utilities;

@layer reset {
  * { margin: 0; padding: 0; }
}

@layer base {
  body { font-family: sans-serif; }
}

@layer components {
  .button { background: blue; }
}

@layer utilities {
  .mt-4 { margin-top: 1rem; }
}

/* Utilities always win, no !important needed */

Benefit: Utility classes beat components. Components beat base. Predictable, maintainable.
