/* =============================================================================
 * Social Breathalyzer — design system (sb-* classes).
 *
 * Ported from the sb-frontend Astro project so the marketing pages of
 * socialbreathalyzer.ai share one consistent look. Plain CSS, no framework.
 *
 * NAMESPACE: every class in this file is prefixed `sb-` so it can coexist
 * with the legacy style.css (used by upload.html, report.html, etc).
 * Pages that opt in to the new design replace their body content with
 * sb-* markup and drop the legacy class usage.
 *
 * Loaded AFTER /assets/style.css when a page wants the new look.
 * ============================================================================= */
