 * This is a manifest file that'll be compiled into application.css.

 * With Propshaft, assets are served efficiently without preprocessing steps. You can still include
 * application-wide styles in this file, but keep in mind that CSS precedence will follow the standard
 * cascading order, meaning styles declared later in the document or manifest will override earlier ones,
 * depending on specificity.
 *
 * Consider organizing styles into separate files for maintainability.
