/* ==========================================================================
   TourFlow «Horizon» — طبقة الرموز والمكوّنات المقترحة
   المعيار: docs\ui-audit\00-design-standard.md
   ---------------------------------------------------------------------------
   آمن للإسقاط في RumWeb\Content\tf-tokens.css (يُحمَّل بعد tf-ui.css):
   1) كل الرموز أسماء جديدة (--tf-color-*, --tf-space-*, --tf-r-*, --tf-elev-*,
      --tf-font-*, --tf-fs-*, --tf-dur-*, --tf-ease-*, --tf-brand-*) لا تصادم
      الرموز القديمة (--tf-indigo*, --tf-radius*, --tf-shadow*, --theme-*, --ui-*).
   2) كل المكوّنات تحت نطاق الاشتراك .tf-ds فلا تتأثر أي شاشة حالية
      (الأصناف tf-btn/tf-card/tf-table-wrap... موجودة اليوم في القوالب).
   3) لا يلمس عناصر عامة (body, a, button, table) خارج .tf-ds.
   الوضع الداكن: html[data-theme=dark] (الآلية الحالية في _Layout.vbhtml).
