Remove duplicate css properties

Editor assessment

Short, specific, and mostly well-typed. 'remove duplicate css properties' tells reviewers exactly what to expect, honors the imperative mood, stays lowercase, and omits the period. The `fix(client)` classification is the debatable part: eliminating redundant declarations is cleanup — `refactor` or even `style` — unless the duplicates demonstrably produced wrong cascade behavior, which this message doesn't establish. With no body, the reader can't tell whether a visual bug was fixed or lint warnings silenced, and that distinction changes whether tooling owes users a patch release. The subject earns its keep; the justification is what's absent.
