PostCSS Selector Lint

PostCSS Selector Lint is a v1.0.2 PostCSS plugin that warns about disallowed CSS selector types (type, class, id, universal, attribute, pseudo) in global vs local (nested) scope. It helps prevent scope pollution by flagging non-nested type/tag selectors. The configuration is fully customizable per scope. Release cadence is low; latest version is stable. Key differentiator: scope-aware linting (global vs local) rather than simple selector blacklisting. Alternatives like stylelint offer broader linting but require more configuration.
