/* KulliQ — برمج الروبوت: a coding game for 9 to 12. A navy sky with stars, floating 3D tiles seen a little from the front,
   a robot from above, and the program as coloured blocks: قدّام (green), لف يمين (blue), لف يسار (purple), and «كرّر» (a
   yellow box that holds blocks). The first screen and «المزيد» follow «ذاكرة الصور» (games/memory/memory.css), kept
   here so each game stands on its own. */
