/* The quick quiz on the STUDENT surface (StudentView). Prefix .qz-s-.
   docs/class-app/quizzes/DESIGN.md, "The surfaces".

   PHONE FIRST. The base rules are the phone; 768px and 1025px only add room.
   The panel sits in StudentView's column (`.cl-student`, 44rem at most), so a
   laptop sees the same stack of cards, centred, rather than a second layout.

   RIGHT AND WRONG ARE NEVER A COLOUR ALONE. Blue (`--primary-color`) and red
   (`--alert-color`) mark them, and every such mark also carries a shape (the
   icon) and a word ("נכונה", "לא נכון"), because a colour is not a sentence for
   somebody who cannot tell the two apart. No brand gradient on this sheet:
   nothing here is a thin rule, and a filled or bold shape must not wear it.

   Every tap target is at least 44px: the options and the order rows by their
   minimum height, the drag handle and the arrows by their size, the Save
   buttons by `min-block-size`. */
