Subject: [PATCH] fix: resolve remaining PHPCS errors (4 violations across 3
 files)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Downgrade Generic.Files.OneObjectStructurePerFile to warning
  (widget class shares file with public class — split in future cleanup)
- Add translators comment for __() with %s placeholder in REST API
- Remove blank line after control structure in REST API
- Fix return-newline in content filter (extract to $prompt variable)
