Problem

Component libraries simplify UI work—until their styles start winning every time. Product tweaks become an arms race: nested selectors, extra classes, and the occasional !important to force a visual change. That creates brittle overrides and long-term maintenance pain.

Implementation (what to do)

1) Declare a stable @layer order and keep it explicit in your imports or build. Make sure the library layer is declared earlier and the site (product) layer declared later.

2) Wrap or import third-party library CSS into the earlier layer. Keep product/theme overrides and page-specific rules in the later layer.

3) When authoring site rules, prefer short, descriptive selectors (type, single class) or use :where() to scope matches without increasing specificity.

Expected behavior

For normal (non-!important) declarations, layer precedence is evaluated before selector specificity.…
