PostCSS Banner

PostCSS plugin to prepend a banner and/or append a footer text comment to the resulting CSS file. The current stable version is 4.0.1, with no frequent releases (last major release in 2020). It provides options for inline single-line comments or multi-line styled comments, and supports `important` flag to preserve banners during minification (e.g., /*! … */). Unlike manual string concatenation, it integrates seamlessly into PostCSS pipeline and respects plugin ordering.
