/* شهاب — files: ملفات شهاب.

   صفحة تحريرية فاتحة بترتيب واحد: هيرو «مكتب الملفات» على ورق الملفات الدافئ
   (يمين: المسار والعنوان والوصف ثم الملف المفتوح بعنوانه ووصفه وثلاث مواد منه
   وزرّه؛ يسار: غلافه الكبير — الغلاف الحاد الوحيد عندنا، 900px — وتحته
   «ملفات مفتوحة أيضًا»؛ العمودان يبدآن وينتهيان على نفس الخط)، «آخر الملفات»، «ملفات تفاعلية» كتلتين فاتحتين
   (الخريطة ومكتب البيانات، والرقم الحي كبير من js/figures.js)، و«من أرشيف شهاب»
   صف من 4. البطاقة .sh-reveal (components.css): الغلاف وحده، والعنوان والتاريخ يطلعوا
   عليه مع الهوفر. أغلفة الموقع القديم 452×267 على الأكثر،
   فمفيش بطاقة أعرض من ~400px على اللابتوب. على الموبايل البطاقات صفوف
   (غلاف صغير جنب العنوان). لا ترقيم ولا لافتات ولا خطوط زمنية مزخرفة. */
