/* =====================================================================
 * SmartNail — Admin Dashboard styles.
 *
 * Design tokens come from css/brand.css (source docs/BRAND.md,
 * "Blush & Rose Gold"). That file ships tokens inside an @theme block
 * (CSS Cascade Layers), which browsers do not implement, so the exact
 * BRAND.md values are bound to :root here — same values, same source
 * (same approach as src/salon/style.css).
 *
 * Brand rules applied (BRAND.md): warm ivory surfaces, deep rose only
 * for interaction/emphasis, pill buttons (999px), 16px card corners,
 * soft warm shadows, Be Vietnam Pro stack with system fallbacks.
 * Mobile-first, single column; desktop gets the tab bar + tables.
