Why use cascade layers?
Layers let you organize reset, library, component, and utility styles with an explicit order.
The first layer order declaration wins for those named layers, so a later file cannot silently reorder the system.
Layer precedence is separate from selector specificity, which makes overrides easier to reason about.
Cascade layer questions
What order should I use?A common starting point is reset, base, components, utilities; choose the order that matches your project contract.
Can I rename the layers?Yes. Names are project vocabulary, so use terms your team will recognize.
Does this add my existing rules?No. It gives you the structure; paste each existing rule into its matching named block.
