/*
 * 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.
 *
 * This file is unlayered CSS, so it wins over the Tailwind build's layered
 * rules (theme/base/utilities) regardless of load order — the app-wide state
 * rules below rely on that. Design tokens (--color-*) come from the Tailwind
 * @theme and are readable here as plain custom properties.
