Bad

The .card .title descendant selector repeats the parent selector in a flat rule.

<style scoped>
.card .title { color: red; }
</style>

Good

The .title rule is nested inside .card, keeping the parent-child styling relationship together.

<style scoped>
.card { .title { color: red; } }
</style>

Good avoids this rule's finding under the configuration above; other rules may still report diagnostics.
