/* Teaching with EduCS (/teaching/, 2026-10-25).
   Three ways to use a lesson, each a card whose small scene acts its idea
   out when the card is pointed at (the app's "Your first hour" pattern),
   with the how as numbered beats; then two tiles for the guides and the
   school pilot. Each card has its own brand colour in --scene. Touch
   screens and reduced motion show each scene in its finished state. */
