CSS @layer for cascade control

CSS specificity wars make it hard to override third-party styles or maintain a clean architecture.

Use @layer to control cascade priority independent of specificity:

/ Define layer order - last wins /
@layer reset, base, components, utilities;

@layer reset {
* { margin: 0; padding: 0; box-sizing: border-box; }
}

@layer base {
h1 { font-size: 2rem; color: #333; }
}

@layer components {
.card h1 { color: blue; } / Higher priority than base /
}

@layer utilities {
.text-red { color: red !important; } / Highest priority /
}

/ Unlayered styles beat ALL layers /
h1.special { color: green; }

Layers let you organize CSS by purpose rather than fighting specificity. The order of @layer declarations determines priority.
