/**
 * Default Brand Stylesheet
 *
 * This file serves as the base stylesheet applied across all brands.
 * Any CSS defined here acts as the foundational layer that every brand
 * inherits by default. Brand-specific overrides should live in their
 * respective brand directories — not here.
 *
 * Use this file for styles that are truly universal and brand-agnostic.
 * Dependency chain:
 *   default/vars.css → brands/<brand>/vars.css → default/styles.css (this file)
