A scope root limits which descendants a selector can match, keeping component rules close to their intended markup.

An optional limit creates a boundary inside the root, useful when a nested region should keep its own styles.

Scoping proximity helps a closer scope win when scoped rules compete, without rewriting every selector with extra specificity.

What should the root be?

Use the component's class or attribute, such as .card or [data-component='card'].

What does the limit do?

It stops the scope from reaching past a matching descendant, such as .card__footer.

Does @scope change specificity?

The at-rule adds scoping behavior; the selectors inside retain their normal specificity.
