/* إحراز — «ابنِ مقالك خطوة بخطوة»: the path (writing-guided.html), one essay (writing-essay.html), the drills
   (writing-drills.html) and the hub's third door (writing.html). Built on reading-lessons.css (the lesson page
   and the lessons list). Pink is writing's colour; gold only marks the step or essay to do next; right is
   green and wrong is peach, as everywhere. Motion is for presses and answers only: a ripple, a pop or a shake,
   and a new step rising in. */
