   spaces — «المساحات» (1.16، القدرة spaces): شاشة المساحة (screens/space.js)، والحبّة «أنت في مساحة»
   (ui/space-pill.js)، وورقة «مساحة جديدة» (ui/space-create.js) وأوراق الأشخاص والإعدادات. شريط «مباشر الآن» في
   الساحة نفسها في saha.css (.sa-spc-*)، والتعليقات والتفاعلات المتحركة في ملف الطبقة (ui/space-live.js).
   الشاشة سطح أزرق ليلي هادئ في السمتين (كسطح المكالمة الداكن الدائم): رموزها تُعاد تعريفها داخل .sp-screen فتتبعها
   مكوّنات ui.css كما هي (.btn .icon-btn .av). الحركة transform/opacity وحدهما، وتقف كلها مع prefers-reduced-motion.
